Answer 1

Hi ,

Principal = P = Rs 2400

Rate of interest ( I ) = 12%

Time = T = 2 1/2 years = 5 /2 years

Amount = A

We know that ,

A = P ( 1 + TR /100 )

= 2400[ 1 + (5 × 12)/(2 × 100 )]

= 2400 × [ ( 100 + 60 ) /200 ]

= 2400 × 160 /200

A = RS 3120

According to the problem given ,

1200 + cost of cow = A


Cost of the cow = 3120 - 1200

= Rs 1920
