Answer: (2) Rs.11,900
Explanation:-

Given-  Principal = Rs.5,000,         Amount = Ra.5,700     and time = 1 year
Simple interest = A mount – Principal
=   5,700 – 5,000 = 700
Formula-  Simple interest = Principal x time x rate /100
Then, Rate = 700 x 100/5000 x 1
= 14%
And  the interest of 5 years of Rs.7000 –
Simple interest = 14 x 5 x 7000/100
= Rs.4,9,00
Then, the amount will be end of the five years = 7,0,00 + 4,900 = 11,900

Hence, the answer is (2) Rs.11, 900.
