a certain sum amounts to rs.7350 in 2 years and to rs.8575 in 3 years.find the sum and rate ercent.

Correct Answer : A.

S.I on rs.7350 for 1 year=rs.(8575-7350)=rs.1225.

Rate=(100*1225/7350*1)%=16 2/3%

Let the sum be rs.x.then,

X(1+50/3*100)²=7350

X*7/6*7/6=7350

X=(7350*36/49)=5400.

Sum=rs.5400.
