Question

The difference between the C.I. and S.I. on the sum of money for 2 years at $12\%$ p.a. is Rs. 150. The sum is?

• A. Rs. 9000
• B. Rs. 9200
• C. Rs. 9500
• D. Rs. 9600

Answer 1

C.I - S.I = 150
$[P{(1+\frac{R}{100})}^2-P]-\frac{PRT}{100}=150$
$P[1+\frac{R^2}{10000}+\frac{2R}{100}-1-\frac{2R}{100}]=150$
$\frac{P{R}^2}{10000}=150$
Put the value of R and get the answer
