RBI Grade B Officers 22 Nov 2015 Paper

A certain amount is invested in scheme A for 6 years which offers simple interest at the rate of x % per annum. The same amount is invested in scheme B for 2 years which offers compound interest compounded annually at the rate of 10% per annum. Interest earned from scheme A is twice to that earned from scheme B. If the rate of interest of scheme A had been (x + 2)% per annum, the difference between the interests after corresponding periods would have been Rs. 3960. What is the amount invested in each scheme?
