उत्तर

P = Rs 20,000 ; t = 2 years ; r = `12 1/4 %` and `5 1/2 %` successively = `49/4`% and `11/2` % successively.

`"A" = "P" (1 + "r"/100)^"n"`

A = Rs 20000 `(1 + 49/(4 xx 100)) (1+ 11/(2 xx 100))`

= Rs 20, 000 x 1. 1225 x 1. 055

=Rs 23,684.75 

C.l. = A - P

= Rs (23,684.75 - 20, 000)

=Rs 3,684.75 

Hence, Amount= Rs 23,684.75 and C.I. =Rs 3,684.75.
