उत्तर

Installment per month (P) = Rs. 600

Number of months (n) = 20

Rate of interest (r) = 10% p.a.

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

= `600 xx (20(20 + 1))/(2 xx 12) xx 10/100`

= `600 xx 420/24 xx 10/100`

= Rs. 1,050

The amount that Manish will get at the time of maturity

= Rs. (600 × 20) + Rs. 1,050

= Rs. 12,000 + Rs. 1,050

= Rs. 13,050
