Expert Answer:

Let x be the principal.

Given: Amount = Rs. 10,370, Rate = 11% and Time = 2 years

Simple interest = Amount - Principal

Simple Interest = 10370-x

Simple interest =fraction numerator P cross times N cross times R over denominator 100 end fraction

10370 minus x equals fraction numerator x cross times 2 cross times 11 over denominator 100 end fraction

x equals 8500

Now we need to find what will it amount to in 3 years at the same rate

Now, Principal = Rs. 8500, Time = 3 years, Rate = 11%

S I equals fraction numerator P cross times N cross times R over denominator 100 end fraction equals fraction numerator 8500 cross times 11 cross times 3 over denominator 100 end fraction equals 2805

Amount = Principal +Interest

Amount =8500 +2805

Amount =11305

Hence it amount to Rs.11305 in 3 years at the same rate
