Answer 1

Answer:

rs. 117

Step-by-step explanation:

let the price of cow be X

a/q,

X+6=X+ 5% of X

=>X +6= X+ 5/100×X

=>X+6=X+X/20

=>X+6=21X/20

=> 20(X+6)= 21X

=>20X+120=21X

=> X= 120.

A/Q,

purchase price of cow= 2.5% loss

= X-2.5% of X

=120- 2.5% of 120

=120- 2.5/ 100×120

= 120-3

=117 rupees
