If 27 men can do a piece of work in 40 days by working for 6 hours then find in how many days 36 men can do the same work by working 5 hours a day?
Correct
Answer c
Let the number of days required be x
According to the question,
27*40*6= 36*5*x
x= (27*40*6)/(36*5)
x= 36 days
Incorrect
Answer c
Let the number of days required be x
According to the question,

Question 12 of 20
12. Question
The salary of A is 80% more than B while the salary of C is 25% less than the total salary of A and B together then find what is the salary of C if B’s salary is Rs. 45000?
Correct
Answer a
Salary of A = 45000*180/100= Rs. 81000
Salary of A and B together = 81000 + 45000 = Rs. 126000
Salary of C = 126000*75/100 = Rs. 94500
Incorrect
Answer a
Salary of A = 45000*180/100= Rs. 81000
Salary of A and B together = 81000 + 45000 = Rs. 126000
Salary of C = 126000*75/100 = Rs. 94500
Question 13 of 20
13. Question
The average age of two persons is 46 years. 16 years back, the ratio between their ages were 1 : 2, then what is the difference between present ages of these two persons?
Correct
Answer b
The average age of two persons = 46 years
Total present age of two persons = 46*2 = 92 years
16 years back, the ratio between their ages = 1 : 2(x, 2x)
According to the question,
X+ 16 + 2x + 16 = 92
3x + 32 = 92
3x = 60
X = 20
The present age of two persons = x + 16, 2x + 16 = 36, 56
Required difference = 56 – 36 = 20 years
Incorrect
Answer b
The average age of two persons = 46 years
Total present age of two persons = 46*2 = 92 years
16 years back, the ratio between their ages = 1 : 2(x, 2x)
According to the question,
X+ 16 + 2x + 16 = 92
3x + 32 = 92
3x = 60
X = 20
The present age of two persons = x + 16, 2x + 16 = 36, 56
Required difference = 56 – 36 = 20 years
Question 14 of 20
14. Question
Find the respective ratio of the volumes of a sphere and a cylinder, both having radius 14cm and the height of the cylinder is 16 cm.
Correct
Answer b
Volume of the sphere = 4/3πr^{3} = 4/3 x 22/7 x 14 x 14 x 14
Volume of the cylinder = πr^{2}h = 22/7 x 14 x 14 x 16
Required ratio = (4/3 x 22/7 x 14 x 14 x 14): (22/7 x 14 x 14 x 16) = 7:6
Incorrect
Answer b
Volume of the sphere = 4/3πr^{3} = 4/3 x 22/7 x 14 x 14 x 14
Volume of the cylinder = πr^{2}h = 22/7 x 14 x 14 x 16
Required ratio = (4/3 x 22/7 x 14 x 14 x 14): (22/7 x 14 x 14 x 16) = 7:6
Question 15 of 20
15. Question
Difference between Simple interest and Compound interest on a certain sum at the rate of 20% per annum for two years is Rs.1680. Find the simple interest on that sum at the rate of 14% per annum after 8 years.
Correct
Answer d
We know that, the difference between CI and SI for two years is
Difference = P*(r/100)^{2}
=> 1680 = P*(20/100)^{2}
=> 1680 = P*(1/5)^{2}
= > 1680 = P*(1/25)
=> P = Rs. 42000
SI = (42000 x 14 x 8)/100 = Rs. 47040
Incorrect
Answer d
We know that, the difference between CI and SI for two years is
Difference = P*(r/100)^{2}
=> 1680 = P*(20/100)^{2}
=> 1680 = P*(1/5)^{2}
= > 1680 = P*(1/25)
=> P = Rs. 42000
SI = (42000 x 14 x 8)/100 = Rs. 47040

Answer b
30 % of 5400 + 68 % of 4100 = x – 2168
(30/100)*5400 + (68/100)*4100 = x – 2168
1620 + 2788 + 2168 = x
X = 6576 = 6580

Answer a
Salary of A = 45000*180/100= Rs. 81000
Salary of A and B together = 81000 + 45000 = Rs. 126000
Salary of C = 126000*75/100 = Rs. 94500
Answer b
The average age of two persons = 46 years
Total present age of two persons = 46*2 = 92 years
16 years back, the ratio between their ages = 1 : 2(x, 2x)
According to the question,
X+ 16 + 2x + 16 = 92
3x + 32 = 92
3x = 60
X = 20
The present age of two persons = x + 16, 2x + 16 = 36, 56
Required difference = 56 – 36 = 20 years
Answer b
Volume of the sphere = 4/3πr^{3} = 4/3 x 22/7 x 14 x 14 x 14
Volume of the cylinder = πr^{2}h = 22/7 x 14 x 14 x 16
Required ratio = (4/3 x 22/7 x 14 x 14 x 14): (22/7 x 14 x 14 x 16) = 7:6
Answer d
We know that, the difference between CI and SI for two years is
