Question

What is the rate per cent if ₹ 1600 amounts to ₹ 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 = ₹ 1600, A = ₹ 1900 and T = 2.5 years

I = A−P

= ₹ 1900− ₹ 1600

=₹ 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
