उत्तर
Let monthly instalment is Rs P
here n = 1 year = 12 months
n = 12
∵ M.V. = `("n"("n" + 1))/(2 xx 12) xx ("P" xx "R")/(100) + "P"."n"`
⇒ ₹ 6455 = `(12(12 + 1))/(2 xx 12) xx ("P" xx 14)/(100) + "P".12`
₹ 6455 = `(13 xx "P" xx 7)/(100) + "P".12`
⇒ ₹ 6455 = `(91"P" + 1200"P")/(100)`
⇒ ₹ 645500 = 1291P
⇒ P = `(645500)/(1291)`
= ₹ 500.
