1.  ₹ 800 becomes Rs. 956 in 3 years at a certain rate of simple interest. If the rate of interest is increased by 4%, what amount will ₹ 800 become in 3 years ?
A. ₹ 1020.80
B. ₹ 1025
C. ₹ 1052
D. Data inadequate
E. None of these

Answer: Option C

Explanation:

S.I. = ₹ (956 - 800) = ₹ 156.

∴ Time = 100 x 156 years = 3 years.
800 x 3

= 6%

New Rate = 6 + 4% = 10%.

New S.I. = ₹ (800 x 21/2 x 3/100)

= ₹ 252.

New amount = ₹ (800 + 252) = ₹ 1052
