Option 4 : Rs. 6000

**Given:**

Amount = Rs. 9375

Time = 2 years

Rate of interest = 25%

Formula used:

A = P(1 + R/100)T

Where,

A = Amount, P = Principal,

R = Rate of interest, T = Time

Calculation:

According to the question,

A = 9375

⇒ P(1 + R/100)T = 9375

⇒ P(1 + 25/100)2 = 9375

⇒ P(1 + 1/4)2 = 9375

⇒ P(5/4)2 = 9375

⇒ P(25/16) = 9375

⇒ P = 375 × 16

⇒ P = 6000

**∴ The sum is Rs. 6000.**

As rate of interest is 25% = 1/4

So principal of 4 will increase by 1 to give amount 5.

Here 25 corresponds to 9375

⇒ 1 will corresponds to 9375/25 = 375

⇒ 16 will corresponds to 16 × 375 = 6000

∴ The sum is Rs. 6000.
