Question 3 |
The sum of a number and its inverse is –4. The sum of their cubes is:
A | -52 |
B | 52 |
C | 64 |
D | -64 |
Question 3 Explanation:
Given : a + 1/a = - 4
Find: a^3 + (1/a)^3
Solution: a + 1/a = -4
Take cube on both sides
(a + 1/a)^3 = (-4)^3
a^3 + (1/a)^3 + 3*a* 1/a (a+1/a) = -64
a^3 + (1/a)^3 + 3(a+1/a) = -64
a^3 + (1/a)^3 - 12 = -64
a^3 + (1/a)^3 = - 64 + 12
a^3 + (1/a)^3 = -52
Find: a^3 + (1/a)^3
Solution: a + 1/a = -4
Take cube on both sides
(a + 1/a)^3 = (-4)^3
a^3 + (1/a)^3 + 3*a* 1/a (a+1/a) = -64
a^3 + (1/a)^3 + 3(a+1/a) = -64
a^3 + (1/a)^3 - 12 = -64
a^3 + (1/a)^3 = - 64 + 12
a^3 + (1/a)^3 = -52
Question 4 |
A certain principal invested at compounded interest payable yearly amounts to Rs. 10816.00 in 3 years and Rs. 11248.64 in 4 years. What is the rate of interest?
A | 3% |
B | 4% |
C | 4.5% |
D | 5.5% |
Question 4 Explanation:
Rate of interest=((11248.64 - 10816)/10816) * 100
= (432.64 / 10816)*100
= 4%
= (432.64 / 10816)*100
= 4%

Question 6 |
What is the exact equivalent discount of three successive discounts of 10%, 15% and 20% by sale of an article?
A | 35.8% |
B | 38.5% |
C | 35.5% |
D | 38.8%
|
Question 6 Explanation:
Single equivalent discount for successive discounts of 10% and 15%.
= (10+15- (15*10)/100)%
= 23.5%
Single equivalent discount for 23.5% and 20%
=(23.5+20-(23.5*20)/100)%
=38.8%
= (10+15- (15*10)/100)%
= 23.5%
Single equivalent discount for 23.5% and 20%
=(23.5+20-(23.5*20)/100)%
=38.8%

|
C | ₹ 15000 and ₹ 5000 |
D | ₹ 18000 and ₹ 6000 |
Question 28 Explanation:
5%P = (15/100)*Q
(10/100)*Q = (20/100)*R
(20/100)*2000
=4000
(10/100)*Q = 4000
Q = 4000
(5/100)*P = (15/100)*4000
=600
P = (600*100)/5
P=12000
(10/100)*Q = (20/100)*R
(20/100)*2000
=4000
(10/100)*Q = 4000
Q = 4000
(5/100)*P = (15/100)*4000
=600
P = (600*100)/5
P=12000

Question 38 |

A | 6 hours |
B | 15 hours |
C | 18 hours
|
D | 24 hours
|
Question 38 Explanation:
Three pipes fill a tank in 4 hours
P1 takes 8 hours and in one hour work is 1/8
P2 takes 12 hours and and in one hour work is 1/12
P3 takes x hours and and in one hour work is 1/x
Amount of work done by both p1 and p2=(⅛+1/12+1/x)=5/24+1/x
Now 1/x=1/4-5/24=6-5/24=1/24
P3 will take 24 hours to fill the tank
P1 takes 8 hours and in one hour work is 1/8
P2 takes 12 hours and and in one hour work is 1/12
P3 takes x hours and and in one hour work is 1/x
Amount of work done by both p1 and p2=(⅛+1/12+1/x)=5/24+1/x
Now 1/x=1/4-5/24=6-5/24=1/24
P3 will take 24 hours to fill the tank
Question 39 |
The ratio of ages of two persons A and B is 3 : 4 and that of ages of B and C is 4 : 5. If the average of all three is 40 years, what is B’s age?
A | 20 years
|
B | 30 years |
C | 40 years
|
D | 50 years
|
Question 39 Explanation:
Ration of ages of three persons= A:B:C= 3:4:5
Average of three is 40 years
What is the B’s age=?
We can’t get more than 120 as their age because the average of 3 persons is 40.
B is elder than A and younger than C
= 20+40+60
= 120
Average = (120/3)=40
Average of three is 40 years
What is the B’s age=?
We can’t get more than 120 as their age because the average of 3 persons is 40.
B is elder than A and younger than C
= 20+40+60
= 120
Average = (120/3)=40
Question 40 |
In a 100 meters race, A beat B by 10 meter or 2 second. What is the speed of A?
A | 5 Km/h |
B | 10 Km/h |
C | 15 Km/h
|
D | 20 Km/h
|
Question 40 Explanation:
When A completes 100m, B is at 90m which is 10m behind.Now A beats B by 2 secs.
This means B takes 2 more seconds to complete the race
As B is 10m behind when A completes the race, so B takes 2 secs to complete 10m
Speed of B = 5m/s
Total time of B = 100/5 = 20 secs
Time of A = 20 - 2 = 18 seconds
Speed of A = 100/18 = 5.555
This means B takes 2 more seconds to complete the race
As B is 10m behind when A completes the race, so B takes 2 secs to complete 10m
Speed of B = 5m/s
Total time of B = 100/5 = 20 secs
Time of A = 20 - 2 = 18 seconds
Speed of A = 100/18 = 5.555
