Give Mary’s stickers are `x (x >0)`
Peter’s sickers are `3x`
Peter has 60 stickers more than Mary has so
`3x – x = 60`
`2x = 60`
`x = 30`
⇒ `3x = 3×30 = 90`
Therefore , Peter has `90` stickers
Mary has `30` stickers
Give Mary’s stickers are x(x>0)x(x>0)
Peter’s sickers are 3x3x
Peter has 60 stickers more than Mary has so
3x-x=603x-x=60
2x=602x=60
x=30x=30
⇒ 3x=3×30=903x=3×30=90
Therefore , Peter has 9090 stickers .
Mary has 3030 stickers.
