A farmer borrowed Rs.2400 @12% interest per annum. At the end of 2and1/2 years, he cleared his account by paying Rs.1200 and a cow. What is the cost of the cow?

2
Principal = 2400
here principal = 2400
Rate of interst = 12 per annum
time = 2.5 years

First we will calculate simple interest
SI = p*R*T/100;
= 2400 *12*2.5/100
= 720.

SO Total amount To PAy at the end of 2.5 years= Principal + Simple Interest
= 2400 +720
= 3120

The borrower pays 1200 and Cow.
therefore ,
1200+COst of Cow = 3120
cost of cow = 3120 - 1200
Cost of cow = 1920.

Thanks You.

Interest=p*r*t/100
2400*12*2.5/100=720
so,interest=720rs
cost of cow=1200+720=1920rs
