Answer 1

Step-by-step explanation:

13.Principal ( money borrowed)= 12600

Rate of interest=15 ℅ per annum

Time =3 years

Money given after 3 gears is 7070 and a goat

so we will find first the simple interest

12600×15/100×3=5670

Hence total amount is 12600+5670 which is 18720=7070 +goat

18720-7070=goat

11200=goat price
