Solution

Rs 16,000 for 3 years at `7 1/2` p.a. 

P=Rs 16,000 ; t = 3 years ; r = `7 1/2` p.a. 

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

A = Rs `16000 (1 + 15/(2 xx 100))^3`

= Rs 16, 000 × 1.07 5 × 1.075 × 1.075

= Rs 19,876. 75 

C.l.= A - P

= Rs (19,876.75- 16,000)

= Rs 3,876. 75 

Hence, Amount= Rs 19,876.75 and C.I. =Rs 3,876.75
