Answer 1

Answer:

A school has 32classrooms, 15 of them have 20 chairs each while the rest of the classrooms have 18 chairs each

To find:

how many chairs are there in all?

Solution:

Total number of classrooms = 32

15 of them have 20 chairs each.

=> 15 x 20 = 300 chairs

Remainings classrooms:

32 - 15 = 17

Rest of the classroom have 18 chair each

=> 17 x 18 = 306 chairs

Total number of chairs in all classrooms:

=> 300 + 306

=> 606

Hence, there are total 606 chairs in all.
