Question

If 15 oxen or 20 cows can eat the grass of a field in 80 days, then in how many days will 6 oxen and 2 cows eat the same grass? option 1 : 40 option 2 : 60 option 3 : 100 option 4 : 160

Answer 1

15 oxens= 20 cows

1 oxen = 20/15 cows

according to question,

6 oxens = (20/15)*6 cows= 8 cows

8 cows+2 cows = 10 cows

20 cows can eat the grass of a field in 80 days,So

10 cows can eat the grass of a field in 160 days.(80*2=160)

hope u will understand
