Question

If 60 cows can graze on a field for 12 days, then for how long can 40 cows graze on the same field?​

Answer 1

Answer:

8 days

Step-by-step explanation:

60 cows are grazing on the field for 12 days.

Number of cows                             Number of days

60                                                    12

40                                                   12/60 * 40

                                                   = 1/5 * 40

                                                   = 8 days.

Answer 2

Answer:

by cross multiply

let 60 cows and 12 days = 60/12

let 40 cows and days = 40/x

so, 60/12 x 40/x

60x = 40x12

60x = 480

x = 480/60 = 8

x=8days
