Question

A city has 6,770 recycle bins. The city gives half of the recycle bins to its citizens. The rest of the recycle bins are divided into 23 equal groups for city parks. How many recycle bins are left over?

Answer 1

Total no. of recycle bins = 6770
Remaining recycle bins after half of it given away = 6770/2
= 3385
Remaining recycle bins after division
= Remainder when 3385 is divided by 23
= 4
therefore there are still 4 recycle bins remaining
