Step-by-step explanation:

A postman can sort out 738 letters in 6 hours . How many letter can be sorted in 9 hour

We can use unitary method to solve this problem.

So in 6 hours a postman can sort out 738 letters.

Therefore in 1 hour he will be able to sort 738 / 6 = 123 letters

Now in 1 hour he will sort 123 letters.

Therefore in 9 hours the postman will sort 123 x 9 = 1,107 letters.
