Question

Karthik lent Rs. 15,000 to his friends, one at the rate of 12% and the other at a rate of 6% at simple interest. At the end of 2 years, he received an interest of Rs.1,200. Find the amount lent at 6% interest rate.

• A. Rs. 10,000
• B. Rs. 12,000
• C. Rs. 10,500
• D. Rs. 11,250

Answer 1

The correct option is D Rs. 11,250

Overall intrest rate $=\frac{1,200}{15,000}\times 100=8$%

The ratio is = 1:3.
The money lent at 6% intrest rate = $\frac{3}{4}\times 15000=11,250$
Hence, option (D) is the correct answer.
