There are 63 counters in total.
The total number of counters in box A and box B is 36.
The difference between the number of counters in box A and box C is 10.
Work out the number of counters in each box.

Answer 1

A=17

B=19

C=27

Explanation:

C=63-(A+B)

C=63-36

C=27

A+10=C

A=27-10

A=17

A+B=36

B=36-A

B=36-17

B=19
