Question

vinay bought a cake and cut it into three pieces when he weighed the first piece he found that it was 7g lighter than the second piece and 4g heavier than the third piece. If the whole cake weighed 300g .How much did each of the three pieces weigh ?​

Answer 1

Answer:

First piece = x

Second piece = x +7

Third piece = x-4

Accordingly,

x+x+7+x-4 = 300

3x + 7 - 4 = 300

3x + 3 = 300

3x = 300 - 3

3x = 297

x = 297 / 3

x = 99

• first piece = 99

• second piece = 99 + 7 = 106

• Third piece = 99 - 4 = 95
