Answer» Let Muli's salary be x. Money spent on food = 3/10 of x = 3x/10 Money spent on rent = 2/3 of x = 2x/3 Money left with him = 2100 (3x/10) + (2x/3) + 2100 = x x - (3x/10) - (2x/3) = 2100 ( LCM = 30) 30x/30 - 9x/30 - 20x/30 = 2100 (30x - 9x - 20x ) / 30 = 2100 x/30 = 2100 x = 2100 * 30 = 62,000 Answer: Muli's salary = 62,000 3/10=2100 so 1 =(2100÷3)×10= 7000

Answer»

Let Muli's salary be x.

Money spent on food = 3/10 of x = 3x/10

Money spent on rent = 2/3 of x = 2x/3

Money left with him = 2100

(3x/10) + (2x/3) + 2100 = x

x - (3x/10) - (2x/3) = 2100 ( LCM = 30)

30x/30 - 9x/30 - 20x/30 = 2100

(30x - 9x - 20x ) / 30 = 2100

x/30 = 2100

x = 2100 * 30 = 62,000

Answer:

Muli's salary = 62,000

3/10=2100 so 1 =(2100÷3)×10= 7000
