The simple interest on Rs. 3200 for 2 years at the rate of ’X’ p.c.p.a. is Rs. 832.What would be the simple interest on Rs. 4400 for 3 years at the rate of ’x + 3’ p.c.p.a.?

Answer : Option B

Explanation :

$= frac{{832 imes 100}}{{3200 imes 2}} = 13$ ∴ x = 13° per annum. Case II, Rate = (13 + 3)% per annum = 16% per annum

$= frac{{4400 imes 3 imes 16}}{{100}}$ = Rs. 2112
