find the cost of a cow .simple interest​

Answer 1

Answer:

C.I. = Rs. [8000×(1+10/100)2−8000] = Rs.1680

S.I. = Rs. (8000×10×2100)/100 = Rs.1600

Gain = C.l. - S.I.

=Rs. (1680−1600) = Rs.80

Answer 2

Step-by-step explanation:

SI=p*r*t/100

800*8*9/400

= 144

let the cost of cow be x

8000+144=8144

8144=5300+x

x=8144-5300

=2844
