Usha and Fred collect pencils and stickers. Fred has 44 more stickers than pencils. Fred has 5 times the number of pencils Usha has, and Usha has 25% more stickers than Fred. After Usha gives Fred all of her pencils and Fred gives Usha 75% of his stickers, Fred has 27 more pencils than stickers. Find the number of stickers Usha has at first.

1.25 u + 11 |
6 u |
100% + 25% = 125%
125% x 5 u
=
125100 x 5 u
= 6.25 u
125% x 44
=
125100 x 44
= 55
75% x 5 u
=
75100 x 5 u
= 3.75 u
75% x 44
=
75100 x 44
= 33
If another 27 stickers are given to Fred, he will have equal number of stickers and pencils in the end.
6 u = 1.25 u + 11 + 27
6 u - 1.25 u = 38
4.75 u = 38
1 u = 38 ÷ 4.75 = 8
Number of stickers that Usha has at first
= 6.25 u + 55
= 6.25 x 8 + 55
= 50 + 55
= 105
Answer(s): 105
