This set of Aptitude Questions and Answers (MCQs) focuses on “Time Centered – Set 2”.
1. A man invested x rupees for y years at a rate of 6.2% simple interest. If he received 1.32x rupees after y years, find the value of y.
a) 5.12
b) 5.16
c) 5.18
d) 5.22
View Answer
Explanation: The amount he received = x + the interest he received = x + x * y * 6.2 / 100 = x + 0.062xy = 1.32x
X + 0.062xy = 1.32x, 0.062xy = 0.32x, 0.062y = 0.32, y = 0.32 / 0.062 = 5.16
2. A man invested x rupees for y years at a rate of 33% per annum simple interest. If he received 4.33x after y years, find the value of y.
a) 10
b) 10.5
c) 11
d) 11.5
View Answer
Explanation: The value of y = The interest percentage he received / the rate of interest
The interest he received = 4.33x – x = 3.3x = 330% of x
The rate of interest = 33%
Y = 330 / 33 = 10
3. A man invested x rupees for y years at a rate of 12% per annum simple interest. If he received 7.2x after y years, find the value of y.
a) 51.72
b) 51.27
c) 51.66
d) 51.33
View Answer
Explanation: The value of y = The interest percentage / the rate of interest
The interest received = 7.2x – x = 6.2x = 620% of the amount invested.
The rate of interest = 12%
The value of y = 620 / 12 = 51.66
