Question

7. A herd of cows give 4/7 litres of milk each day. Each cow gives 1/3 of total milk every day. They give 24
litres of milk in six days. How many cows are there in the herd?
​

Answer 1

Answer:

21

Step-by-step explanation:

Cows give milk a day = 4/7 litres

One cow gives 1/3 of total = 1/3*4/7= 4/21 litres a day

Cows give 24 litres in six days, then they give 24÷6= 4 litres a day

Number of cows= 4 ÷ 4/21 = 4*21/4= 21 cows

Answer: 21 cows
