800 Rs. becomes 956 Rs. in 3 years at certain rate of simple interest. If the rate of interest is increased by 4%, what amount will 800 Rs. become in 3 years?
[A]1020.80 Rs.
[B]1025 Rs.
[C]1050 Rs.
[D]1052 Rs.

1052 Rs.
SI = 956 – 800 = 156 Rs.
\therefore Rate = \frac{SI\times 100}{Prin.\times Time}
= \frac{156\times 100}{800\times 3} = 6.5\%\ per\ annum
∴ New rate = 10.5%
\therefore SI = \frac{PRT}{100}
= \frac{800\times 3\times 10.5}{100} = 252\ Rs.
∴ Amount = 800 + 252 = 1052 Rs.
Hence option [D] is correct answer.
