Question

What is the rate per cent if Rs 1600 amounts to Rs 1900 in 2.5 years?

• A. 9.5%
• B. 7.5%
• C. 6.25%
• D. 8%

Answer 1

The correct option is B

7.5%

P = Rs 1600, A = Rs 1900 and T = 212212 years = 5252 years

I = A−P

= Rs 1900−Rs 1600

= Rs 300

Rate = \(\frac{(100 \times I)}{(P \times T)}

= $\frac{(100\times 300)}{(1600\times 2.5)}$

= 7.5 %

Hence, the rate per cent is 7.5
