Question

A farmer wants to transport 100 cows to another farm. Each truck can carry 7cows. He has 10 trucks . How many more trucks does he need?

Answer 1

Answer:

3 more trucks

Step-by-step explanation:

7 cows a truck and 10 trucks equals 70 cows carried. 30 more cows/10 per truck equals 3 more trucks.

Answer 2

Answer:

5 trucks

Step-by-step explanation:

Since 1 truck=7cows

          10trucks=70cows

          remaining cows=100-70

                                      =30cows

       I Truck=7cows

            ?       =30cows

      Number of trucks =30/7

                                     =4.3 and since trucks cannot be in ratio

then we approximate it to 5 trucks
