Show answer & explanation

Correct answer: A

Explanation

  The correct answer is option 1 i.e. 10000

Understanding

Application

Suppose the sum = Rs. X

Interest = Rs. 3225

Rate = 15%

Time = 2 years

We know:

A = P (1 + R/100)T

So,

[X + 3225] = X × (1 + 15/100)2

⇒ X + 3225 = 1.3225X

⇒ X = 10000

Hence,

Sum = Rs. 10000
