Question

Find the amount to be paid at the end of 3 years, if principal is Rs 1800 at 9% p.a.

hintHint:

Use the formula for simple interest and then find the total amount.

The correct answer is: 2286 Rupees


    Complete step by step solution:
    We calculate simple interest by the formula,S I equals fraction numerator P T R over denominator 100 end fraction…(i)
    where P is Principal amount, T is number of years and R is rate of interest
    Here, we have T = 3,R = 9% and P = 1800
    On substituting the known values in (i), we get S I equals fraction numerator 1800 cross times 3 cross times 9 over denominator 100 end fraction
    not stretchy rightwards double arrow S I equals fraction numerator 1800 cross times 3 cross times 9 over denominator 100 end fraction equals 486
    We have SI = 486 Rupees.
    We know the formula for total amount = A = P +SI…(ii)
    where A is the total amount, P is the principal amount and SI is simple interest.
    On substituting the known values in (ii), we get A = 1800 + 486 = 2286
    Hence total amount to be paid after 3 years = A = 2286 Rupees.
