Number of children who received the extra stickers
= 20 - 10
= 10
Total number of extra stickers received by the rest of the children
= 10 x 10
= 100
Total number of stickers given up
= 10 x 2 u
= 20 u
20 u = 100
1 u = 100 ÷ 20 = 5
Total number of stickers for 20 children
= 20 x 5 u
= 100 u
= 100 x 5
= 500
Answer: 500
