Question

help me in solving 20 sum​

Answer 1

Answer:

If a horse and two cows cost 680 rupees

and if only a horse cost 80 rupees

then two cows = 680 - 80 =600

if two cows = 600

then one cow = 600/2 =300 ANS.........

Answer 2

Step-by-step explanation:

let cost of each horse be x

and cost of each cow be y

according to question x+2y=680 (1)

x=80+y (2)

putting value of x from (2) in (1)

80+y+2y=680

600/3=200=y

so, x=280
