Question

Ajay borrows Rs.1500 from two money-lenders. He pays interest at the rate of 12% per annum for one loan and at the rate of 14% per annum for the other. The total interest he pays for the entire year is Rs. 186. How much does he borrow at the rate of 12%?

• A. Rs. 1200
• B. Rs. 1300
• C. Rs. 1400
• D. Rs. 300

Answer 1

The correct option is A Rs. 1200

$P=1500,R_1=12\%,R_2=14$

SI = 186

Let Rs. x be amount invested at 12% Rate

$=\frac{x\times 12\times 1}{100}+\frac{(1500-x)\times 14}{100}=186$

$\frac{21000}{100}-\frac{2x}{100}=186,x=1200$
