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 — The parts are Rs.650 and Rs.900, so that is the answer.
Explanation
★The parts are Rs.650 and Rs.900, so that is the answer.
★Let the amount at 8 percent be x.
★The interest equation is 8x over 100 plus 6 times (1550 minus x) over 100 equals 106.
★This simplifies to 2x over 100 equals 13.
★So x is 650, invested at 8 percent.
★The rest, 1550 minus 650, is 900 at 6 percent.
