Question

I spent 30% on rent, 1/3 on food and remained with $4200. What was my total salary?

Answer 1

30/100 = rent

1/3 = 33.3 = food
remainder = $4200

total spent = 30% + 33.3% = 63.3%
remainder = 100% - 63.3% = 36.7%

therefore if $4200 = 36.7%
then 1% = $4200 / 36.7
= $114.44

so 100% (total salary) = $114.44 x 100
= $11 444.00
