Answer 1

Amount of interest = RS 186

Step-by-step explanation:

Given:

Loan amount = Rs600

Rate = 7% = 0.07

Number of year = 4 year

Find:

Amount of interest

Computation:

Amount of interest = p[(1+r)ⁿ-1]

Amount of interest = 600[(1+0.07)⁴-1]

Amount of interest = 600[(1.07)⁴-1]

Amount of interest = 600[(1.31 - 1]

Amount of interest = 600[(0.31]

Amount of interest = RS 186
