A charity organization has a fund of Rs. 2, 00, 000 to provide annual grants to students. The grant amount each year is Rs. 15, 000. The fund earns an interest rate of r% per annum. If the interest earned is used entirely to provide the grants, then the annual interest rate r is:
- A 8%
- B 7.5%
- C 5.7%
- D 9.2%
Answer & Solution
Correct Answer
(B) 7.5%
Step-by-step Solution
Detailed explanation
\( 15000 = \frac{200000 \times r \times 1}{100} \) \( 15000 = 2000 \times r \) \( r = \frac{15000}{2000} \) \( r = 7.5 \% \)
