उत्तर

Installment per month (P) = Rs. 900

Number of months (n) = 48

Let rate of interest (r) = r% p.a.

∴ `S.I. = P xx (n(n + 1))/(2 xx 12) xx r/100`

= `900 xx (48(48 + 1))/(2xx 12) xx r/100`

= `900 xx 2352/24 xx r/100`

= Rs. (882)r

Maturity value = Rs. (900 × 48) + Rs. (882)r

Given maturity value = Rs. 52,020

Then Rs. (900 × 48) + Rs. (882)r = Rs. 52,020

`\implies` 882r = Rs. 52,020 – Rs. 43,200

`\implies` r = `8820/882` = 10%
