Question

2.
Evan has a collection of 400 stickers.

60% of them are blue and the rest of them are white.
His mother gave him 20 more white stickers and he gave his sister 75% of his blue
stickers.
What percentage of his stickers in the end are white?

Answer 1

Answer:

75%

Step-by-step explanation:

Total no. of stickers Evan has = 400

% of stickers that are blue = 60%

% of stickers that are white = 100% - 60% = 40%

No. of stickers that are blue = 60/100 * 400 = 240

No. of stickers that are white = 400 - 240 = 160

No. of white stickers given to him by his mom = 20

% of stickers blue stickers that he gave to his sister = 75%

No. of blue stickers he gave to his sister = 75/100 * 240 = 180

No. of blue stickers left with him = 240 - 180 = 60

Total no. of white stickers he has = 160 + 20 = 180

Total no. of stickers he has = 180 + 60 = 240

% of white stickers = 75%
