Question

Mohini spend 30% of his salary on the house rent and 20% of the education and of her children and 40% on food items find her salary if she saves rupees1470 per month

Answer 1

let mohini's salary be ₹x
salary spent on house rent= 30% of x
salary spent on children's education = 20% of x
salary spent on food items = 40% of x
money saved = ₹1470
the of all these expenses (inc. money saved) must be equal to her salary
x =
$30 \div 100 \times x + 20 \div 100 \times x \times + 40 \div 100 + x + 1470$
=
$9 \div 10x + 1470$
10x = 9x + 14700
10x - 9x = 14700
x = 14700
mohini's salary = ₹14700
