A person invests Rs.1550 in two parts, one part at 8% and the other at 6%. If the total interest earned in a year is Rs.106, find the amounts invested at each rate respectively.

ARs.650 and Rs.900 ✓ Correct

BRs.700 and Rs.850

CRs.750 and Rs.800

DRs.800 and Rs.750

Correct answer: (A) Rs.650 and Rs.900

Explanation

Rs. 650 is at 8% and Rs. 900 is at 6%.

Let x be invested at 8% and (1550 - x) at 6%.

0.08x + 0.06(1550 - x) = 106.

0.02x + 93 = 106, so 0.02x = 13 and x = 650.

The other part = 1550 - 650 = 900.
