Question 1 |

The difference between the compound interest and the simple earned at the end of 3 rd year on a sum of money at a rate of 10% per annul is Rs. 77.5. What is the sum?

Rs. 3,500 | |

Rs. 2,500 | |

Rs. 3,000 | |

Rs. 2,000 |

Question 1 Explanation:

Let principal be ‘x’

S.I = P T R / 100

S.I = X * 3 * 10 / 100

C.I = [ P (1 + (R / 100)

C.I = [ X (1+ (10 / 100)

C.I = 331X / 1000

Difference between Compound interest and Simple interest is 77.5

( 331X / 1000 ) - ( 3X / 10) = 77.5

31x / 1000 = 77.5

x = 2500.

S.I = P T R / 100

S.I = X * 3 * 10 / 100

C.I = [ P (1 + (R / 100)

^{T}) - P]C.I = [ X (1+ (10 / 100)

^{3}) - X]C.I = 331X / 1000

Difference between Compound interest and Simple interest is 77.5

( 331X / 1000 ) - ( 3X / 10) = 77.5

31x / 1000 = 77.5

x = 2500.

Question 2 |

Aamir and Birju can cut 5000g of wood in 20 min. Birju and Charles can cut 5000g of wood in 40 min. Charles and Aamir cut 5 kg of wood in 30 min. How much time Charles will take to cut 5 kg wood alone?

120 min | |

48 min | |

240 min | |

120 min |

Question 2 Explanation:

Here in this question 5000g means 5kg only

So from that question Aamir (A) Birju (B) Charles (C)

Let Aamir, Birju and Charles alone can complete the work in A, B and C minutes respectively, then

1 min. work of (A+B)=1/20, (B+C)=1/40 and (C+A)=1/30

A + B + C = 13/240

1 min. work of C = (A+B+C) - (A+B) = 13/240 - 1/20 = 1/240

So C alone can complete the work in 240 min.

So from that question Aamir (A) Birju (B) Charles (C)

Let Aamir, Birju and Charles alone can complete the work in A, B and C minutes respectively, then

1 min. work of (A+B)=1/20, (B+C)=1/40 and (C+A)=1/30

A + B + C = 13/240

1 min. work of C = (A+B+C) - (A+B) = 13/240 - 1/20 = 1/240

So C alone can complete the work in 240 min.

Question 3 |

An alloy contains copper and zinc in the ratio 5 : 3 and another contains copper and tin in the ratio 8 : 5, If equal weights of the two are melted together to form a 3 rd alloy, find the weight of tin per kg in the new alloy.

40/129 | |

5/13 | |

5/26 | |

28/5 |

Question 3 Explanation:

Amount of copper in first alloy is 5x/8 and zinc is 3x/8.

Amount of copper in second alloy is 8x/13 and tin is 5x/13.

So after mixing tin is available in 2 alloy only that means in 3rd alloy 5x/13/2x

Tin present in 3rd alloy is 5/26.

Amount of copper in second alloy is 8x/13 and tin is 5x/13.

So after mixing tin is available in 2 alloy only that means in 3rd alloy 5x/13/2x

Tin present in 3rd alloy is 5/26.

Question 29 |

Irvin sold a book at a profit of 12%. If Irvin had sold it for Rs. 18 more, then 18% would have been gained. Find the cost price.

Rs. 600 | |

Rs. 300 | |

Rs. 400 | |

Rs. 200 |

Question 29 Explanation:

Explanation: Let CP = 100%

Sold on 12% profit means sold on 112%

now 18% would have been gained means 118% if Rs 18 was more it means 118% - 112% = 18 Rs

so 6%=18Rs

so 100% = (18/6)×100 = 3× 100 = 300 Rs

CP = 300

Sold on 12% profit means sold on 112%

now 18% would have been gained means 118% if Rs 18 was more it means 118% - 112% = 18 Rs

so 6%=18Rs

so 100% = (18/6)×100 = 3× 100 = 300 Rs

CP = 300

Question 30 |

In a group of 7 people, the average age is found to be 17 years. Two more people joined with an average age 19 years. One person left the group whose age was 25 years. What is the new average age of the group?

17.5 Years | |

16.5 Years | |

18 Years | |

16 Years |

Question 30 Explanation:

7 people, the average age is found to be 17 years means 17 * 7 = 119

Two more joined with an average age 19 years means 19 * 2 = 38 So total is 157

But one person left from that group whose age is 25 years 157 - 25 = 132

Remaining average of 8 people is 132 / 8

16.5 Year

Two more joined with an average age 19 years means 19 * 2 = 38 So total is 157

But one person left from that group whose age is 25 years 157 - 25 = 132

Remaining average of 8 people is 132 / 8

16.5 Year

Question 31 |

A 300 meter long metro train crosses a platform in a metro station in 39 seconds while it crosses a lamp post in 18 seconds. What is the length of the platform?

250 meter | |

350 meter | |

520 meter | |

300 meter |

Question 31 Explanation:

Speed = Distance/time = 300/18 = 50/3 m/sec

Let the length of the platform be x meters

Distance = Speed * Time

x+300 = (50/3) * 39

x = 350

Let the length of the platform be x meters

Distance = Speed * Time

x+300 = (50/3) * 39

x = 350

Question 32 |

Assume that a sum of money is divided equally among n girls. Each girl will receive $ 60. If another girl is added to the group and the sum is divided equally among all the girls, each child girl a $ 50 share. What is the sum of money?

$ 3000 | |

$ 300 | |

$ 110 | |

$ 10 |

Question 32 Explanation:

From that question 60 * n = 50 (n + 1)

n = 5

so sum of money is 60 * 5 = 300

n = 5

so sum of money is 60 * 5 = 300

Question 33 |

A tank can be filled by one tap in 10 minutes and by another in 30 minutes. Both the taps are kept open for 5 minutes and then the first one is shut off. In how many minutes more is the tank completely filled?

5 | |

7.5 | |

10 | |

12 |

Question 33 Explanation:

A tank can be filled in 10 mins

another one is in 30 mins and those taps are opened for 5 mins

so in one min one tap is 1/10 another one is 1/30

both can tank open for 5 mins so (1/10 + 1/30 ) * 5

= (2/15) * 5

= 10/15

= 2⁄3

Remaining work is 1- (2⁄3)

= 1⁄3

The left work has to be done by first Tap because first is shut off.

Work will be completed by Second Tap in= (1⁄3) * 30 = 10

another one is in 30 mins and those taps are opened for 5 mins

so in one min one tap is 1/10 another one is 1/30

both can tank open for 5 mins so (1/10 + 1/30 ) * 5

= (2/15) * 5

= 10/15

= 2⁄3

Remaining work is 1- (2⁄3)

= 1⁄3

The left work has to be done by first Tap because first is shut off.

Work will be completed by Second Tap in= (1⁄3) * 30 = 10

Shirin went to a bakery and bought items worth Rs. 25, out of which 30 paise went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?

Rs. 12 | |

Rs. 19.70 | |

Rs. 19.10 | |

Rs. 18.80 |

Question 50 Explanation:

Total cost of the items he purchased = Rs.25

Given that out of this Rs.25, 30 Paise is given as tax => Total tax incurred = 30 Paise = Rs.30/100

Let the cost of the tax free items = x

Given that tax rate = 6%

( 25 - 30/100 - x ) * (6/100) = 30 / 100

6(25−0.3−x)=30

x=25−0.3−5=19.7

Given that out of this Rs.25, 30 Paise is given as tax => Total tax incurred = 30 Paise = Rs.30/100

Let the cost of the tax free items = x

Given that tax rate = 6%

( 25 - 30/100 - x ) * (6/100) = 30 / 100

6(25−0.3−x)=30

x=25−0.3−5=19.7

Question 52 |

Adrian starts a start-up with a capital of Rs. 85,000. Brian joins in the start-up with Rs. 42,500 after sometime. For how much period does Brian join, if the profits at the end of the year are divided in the ratio of 3 : 1?

5 months | |

6 months | |

7 months | |

8 months |

Question 52 Explanation:

Let B joins for X months.

Then,

(Profit of A)/(Profit of B) = 3/1

(85000 * 12)/(42500 *X) = 3/1

85000 * 12 = 42500 * 3 * X

X = 8.

B Joined for 8 months

Then,

(Profit of A)/(Profit of B) = 3/1

(85000 * 12)/(42500 *X) = 3/1

85000 * 12 = 42500 * 3 * X

X = 8.

B Joined for 8 months

Question 53 |

A car travels at an average of 50 miles per hour for 2.5 hours and then travels at a speed of 70 miles per hour for 1.5 hours. How far did the car travel in the entire 4 hours?

210 miles | |

230 miles | |

250 miles | |

260 miles |

Question 53 Explanation:

Speed= 50 miles/ hour Time=2.5 hour

speed=70 miles / hour Time=1.5 hour

Speed= Distance/ time

Distance= speed x Time

=50×2.5+70×1.5

=125+105

=230 miles

speed=70 miles / hour Time=1.5 hour

Speed= Distance/ time

Distance= speed x Time

=50×2.5+70×1.5

=125+105

=230 miles

By selling 45 limes for Rs. 40, a woman loses 20%. How many should she sell for Rs. 24 to gain 20% in the transaction?

16 | |

18 | |

20 | |

22 |

Question 54 Explanation:

SP of 45 limes is Rs.40

loss = 20%

So CP of 45 limes would be 40*100/80= Rs. 50

To gain 20% She should sell these 45 limes for =50*20/100=Rs. 60

Now If she sells for Rs. 60 = 45 limes

So for Rs. 24 he would sell = (24/60)*45 = 18 limes

loss = 20%

So CP of 45 limes would be 40*100/80= Rs. 50

To gain 20% She should sell these 45 limes for =50*20/100=Rs. 60

Now If she sells for Rs. 60 = 45 limes

So for Rs. 24 he would sell = (24/60)*45 = 18 limes
