An amount of Rs.x at compound interest at 20% p.a. for 3 years becomes y. What is y : x?

A) 3 : 1
B) 36 : 25
C) 216 : 125
D) 125 : 216

Correct Answer:



C) 216 : 125

Description for Correct answer:
Given P = Rs.x, r = 20% n= 3 years, A= Rs.y

We know, \( \Large A = P \left(1 + \frac{r}{100}\right)^{n} \)

Therefore, \( \Large y = x \left(1 + \frac{20}{100}\right)^{3} = x \left(\frac{6}{5}\right)^{3} \)

= \( \Large \frac{y}{x} = \frac{216}{125} \)
