Miss C weight before she started her diet is 80 kg.

Solution:

Weight before diet = x

Weight loss percent = 8%

Present weight of Miss C = 73.6 kg

The denominators must be same to add/subtract the fractions.

LCM of 1 and 100 = 100

Multiply first term by and 73.6 by to make the denominator same.

Multiply by 100 on both sides, we get

100x - 8x = 7360

92x = 7360

Divide by 92 on both sides, we get

x = 80

Miss C weight before she started her diet is 80 kg.
