₹ 36 | |

₹ 37.50 | |

₹ 42 | |

₹ 44.25 |

Question 6 Explanation:

Let’s C.P = x

M.P = 120 x / 100

From that question M.P of Magazine is = 180/-

Cost of the paper in a single copy = ?

From the above details we have to find out C.P first

180 x = x (120 x / 100)

After solving this

x = 150

Cost of the paper in a single copy

= 150 * (25/100)

= 37.50

M.P = 120 x / 100

From that question M.P of Magazine is = 180/-

Cost of the paper in a single copy = ?

From the above details we have to find out C.P first

180 x = x (120 x / 100)

After solving this

x = 150

Cost of the paper in a single copy

= 150 * (25/100)

= 37.50

Question 43 Explanation:

Question 44 |

A train started from Mumbai at 6.00 A.M. On the next (second) station 1/3 passengers got down and 96 got in. On the next (third) station, 1⁄2 of the total passengers present in the train, got down and 12 came in. Now there were 248 passengers in the train, when the train started from Mumbai, the number of passengers was :

435 | |

564 | |

654 | |

736 |

Question 44 Explanation:

Let’s take number of passengers in a train = x

on second station 1⁄3 rd passengers got down and 96 got in = (x - (x/3)) + 96

on third station 1⁄2 got down and 12 got in = (((x-(x/3))+96)/2)+12 Now there were 248 passengers

(((x-(x/3))+96)/2)+12 =248

x=564

on second station 1⁄3 rd passengers got down and 96 got in = (x - (x/3)) + 96

on third station 1⁄2 got down and 12 got in = (((x-(x/3))+96)/2)+12 Now there were 248 passengers

(((x-(x/3))+96)/2)+12 =248

x=564

Question 45 |

The LCM of two numbers is 45 times their HCF. If the sum of the LCM and the HCF of these two numbers is 1150 and one of the numbers is 125, then the other number is :

256 | |

225 | |

250 | |

255 |

Question 45 Explanation:

Let the lcm be x and hcf be y and the other number be z.

Given lcm of 2 numbers is 45 times their hcf, the sum of HCF + LCM is 1150.

y = 45x. ---- (1)

x + y = 1150 --- (2)

Substitute equation (1) in (2), we get

46x = 1150

x = 25.

Substitute x = 25 in (1), we get

y = 45 * 25 = 1125.

We know that product of two numbers = LCM * HCF

125 * z = 25 * 1125

z = 25 * 1125/125 = 225.

The other number = 225.

Given lcm of 2 numbers is 45 times their hcf, the sum of HCF + LCM is 1150.

y = 45x. ---- (1)

x + y = 1150 --- (2)

Substitute equation (1) in (2), we get

46x = 1150

x = 25.

Substitute x = 25 in (1), we get

y = 45 * 25 = 1125.

We know that product of two numbers = LCM * HCF

125 * z = 25 * 1125

z = 25 * 1125/125 = 225.

The other number = 225.

Question 48 |

The ratio between Sumit’s and the Prakash’s age at present is 2 : 3. Sumit is 6 years younger than Prakash. The ratio of Sumit’s age to Prakash’s age after six years will be

1 : 2 | |

2 : 3 | |

3 : 4 | |

3 : 8 |

Question 48 Explanation:

Sumit’s age = 2x

Prakash’s age = 3x

Sumit is 6 years younger than Prakash means

Prakash = Sumit + 6

Prakash - Sumit = 6

3x - 2x = 6

x = 6

So, Sumit’s age = 12

Prakash’s age = 18

Ratio of Sumit’s age and Prakash’s age after six years

12+6 : 18+6

18 : 24

3 : 4

Prakash’s age = 3x

Sumit is 6 years younger than Prakash means

Prakash = Sumit + 6

Prakash - Sumit = 6

3x - 2x = 6

x = 6

So, Sumit’s age = 12

Prakash’s age = 18

Ratio of Sumit’s age and Prakash’s age after six years

12+6 : 18+6

18 : 24

3 : 4

Question 49 |

Two pipes A and B can fill a water tank in 20 and 24 minutes respectively and third pipe C can empty at the rate of 3 gallons per minute. If A, B and C opened together filed the tank in 15 minutes, the capacity (in gallons) of the tank is :

60 | |

120 | |

150 | |

180 |

Question 49 Explanation:

Work done by the waste pipe in 1 minute

= (1/15) - ((1/20) + (1/24))

= -1/40 (Negative means it’s emptying)

Volume of the 1/40 = 3 gallons = (40 * 3) = 120 gallons

= (1/15) - ((1/20) + (1/24))

= -1/40 (Negative means it’s emptying)

Volume of the 1/40 = 3 gallons = (40 * 3) = 120 gallons

Question 51 |

A train starts at 7 a.m. from A towards B with a speed of 50 km/hr. Another train from B starts at 8 a.m. with a speed of 60 km/hr towards A. Both of them meet at 10 a.m. at C. The ratio of the distances AC to BC is :

4 : 5 | |

5 : 4 | |

5 : 6 | |

6 : 5 |

Question 51 Explanation:

Distance covered by A in 3 hours with the speed of 50 km/ h is = 50 *3 = 150km

Distance covered by B in 2 hours with the speed of 60 km/ h is = 60 * 2 = 120km =120 km

then AC:BC = 150:120 =5:4

Distance covered by B in 2 hours with the speed of 60 km/ h is = 60 * 2 = 120km =120 km

then AC:BC = 150:120 =5:4

Question 53 Explanation:

Let’s take two numbers x and y

(1⁄4) * (60 / 100) * x = (2⁄5) * (20/100) * y

After solving this one

we got ratios like x : y = 8 :15

(1⁄4) * (60 / 100) * x = (2⁄5) * (20/100) * y

After solving this one

we got ratios like x : y = 8 :15

Question 54 |

A&B together have ₹ 1210. If 4/15 of A’s amount is equal to 2/5 of B’s amount, how much amount does B have ?

₹ 664 | |

₹ 550 | |

₹ 484 | |

₹ 460 |

Question 54 Explanation:

From that question A + B = 1210 ---> (i)

(4/15) A = (2⁄5) B ---> (ii)

(2⁄3) A = B ---> (iii)

Sub (iii) in (i)

A + (2A/3) = 1210

A = 726 (Sub A value in (i) )

So,

B = 484

(4/15) A = (2⁄5) B ---> (ii)

(2⁄3) A = B ---> (iii)

Sub (iii) in (i)

A + (2A/3) = 1210

A = 726 (Sub A value in (i) )

So,

B = 484

Question 56 |

Two dice are thrown simultaneously. The probability of obtaining a total score of 5 is :

1/18 | |

1/12 | |

1/9 | |

None of these |

Question 56 Explanation:

Probability of obtaining a total score of 5 is {(1,4)(2,3)(3,2)(4,1)} = 4

Total Probability = 6 * 6 = 36

P(E) = 4 / 36 = 1 / 9

Total Probability = 6 * 6 = 36

P(E) = 4 / 36 = 1 / 9

Question 57 |

A tradesman marks his goods at such a price that after allowing a discount of 15%, he earns a profit of 20%. Find the marked price of an article which costs him ₹ 850.

₹ 1200 | |

₹ 1300 | |

₹ 1250 | |

₹ 1350 |

Question 57 Explanation:

C.P = 850

M.P = x

Discount = 15%

S.P = x - (15x/100) = 85x / 100

S.P

= 120% of C.P

= (120/100) * 850

= 85 * 12

= 1020

Therefore S.P = (85X/100) = 1020

X = 1200

M.P = x

Discount = 15%

S.P = x - (15x/100) = 85x / 100

S.P

= 120% of C.P

= (120/100) * 850

= 85 * 12

= 1020

Therefore S.P = (85X/100) = 1020

X = 1200

Question 58 |

In a camp, there are meals for 120 men or 200 children. If 150 children have taken their meals, how many men will be catered to with the remaining meal ?

50 | |

40 | |

30 | |

20 |

Question 58 Explanation:

There is a meal for 120 men and 200 children.

150 Children already taken meal. 50 Children remaining can also take a meal

200 Children = 120 men

50 Children = (120/200) * 50

= 30

150 Children already taken meal. 50 Children remaining can also take a meal

200 Children = 120 men

50 Children = (120/200) * 50

= 30

Question 59 |

56 men can complete a piece of work in 24 days. In how many days can 42 men complete the same piece of work ?

48 | |

32 | |

20 | |

16 |

Question 59 Explanation:

1 Men 1 Day work = (1/(56 *24))

42 Men in how many days = (1/(56 *24)) * 42 = 1/32

So,

42 Men can complete piece of work in 32 days.

42 Men in how many days = (1/(56 *24)) * 42 = 1/32

So,

42 Men can complete piece of work in 32 days.

Question 60 |

A boat travels upstream from P to Q and downstream from Q to P in 4 hours. If the speed of the boat in still water is 12 km/hr and the speed of the current is 4 km/hr, then what is the distance from P to Q ?

31 (1/ 3) km | |

41( 1/ 3) km | |

21 (1 /3) km | |

11 (1/ 3) km |

Question 60 Explanation:

Speed of the boat in still water = 12 km/hr

Speed of the current = 4 km/hr

Speed of the upstream = 12 + 4 = 16 km/hr

Speed of the Downstream = 12 - 4 = 8 km/hr

Let the distance between P and Q be x

(x/16) + (x/8) = 4

x = 64 / 3

x = 21 (1⁄3)

Speed of the current = 4 km/hr

Speed of the upstream = 12 + 4 = 16 km/hr

Speed of the Downstream = 12 - 4 = 8 km/hr

Let the distance between P and Q be x

(x/16) + (x/8) = 4

x = 64 / 3

x = 21 (1⁄3)
