(a)
100% + 40% = 140%
140% of blue stickers = 98
100% of blue stickers =
98140 x 100 = 70
100% + 50% = 150%
150% of green stickers = 93
100% of green stickers =
93150 x 100 = 62
Number of stickers at first
= 100% of blue stickers + 100% of green stickers
= 70 + 62
= 132
(b)
Number of stickers in the end
= 98 + 93
= 191
