Answer 1

p=3600 ^ means-multiply.
R=15% P- principle.
T=4yrs. R-rate. T-time. A- amount
si=p^r^t/100
=3600^15^4/100
=2160
A=P+SI
=3600+2160
= 5760
cost of cow = 5760-2160
=1760 ans

Answer 2

Answer:

₹ 1760

Step-by-step explanation:

P = ₹ 3600

R = 15 %

T = 4 Years

S. I. = P × R × T / 100

= 3600 × 15 × 4 / 100

= ₹ 2160

Amount = P + S. I.

= ₹ 3600 + ₹ 2160

= ₹ 5760

The cost of the cow = ₹ 5760 - ₹ 4000

= ₹ 1760
