Question

A sum was put at simple interest at a certain rate for 20 years. Had it been put at 25% higher rate it would have fetched Rs.2600 more. What was the sum?

• A. 520
• B. 620
• C. 720
• D. 820
• E. 920

Answer 1

The correct option is A

520

$\frac{P\times (R+25)\times 20}{100}–\frac{P\times R\times 20}{100}=2600$

$P=520$
