This should be very familiar to P6 students. It is called the excess-shortage problem.

Giving 2 sweets per friend results in having 20 sweets left.


Now ,if you want each friend to have 5 sweets in total, you've got to give each friend 3 more sweets.

But your 20 sweets left is not enough to do that. You need 1 more sweet.

So total you need 20 + 1 = 21 sweets to give to these friends.

Since each friend gets 3 more sweets,

21 ÷ 3 = 7

There are 7 friends.
