Question

A certain sum of money amount rs 756 in 2yr and to rs 873 in 3 1/2 yr find sum and rate of interest

Answer 1

2 yrs - 3.2 yrs =1.5yrs

• S.I. for 1.5 years = Rs 873 - 756 = 117  

• S.I. for 2 years=Rs 117 x 2⁄3 x 2 = Rs 156

Principal=Rs. ( 756 - 156 ) = Rus 600

• P=600

• T=2

• S.I=156

Rate = (100x 156 ⁄ 600 x2) = 52%
