Question

geeta spends 1/3rd of her salary on food and 1/4th on education.if she saves 1200.find his salary ​

Answer 1

Let the total salary of Geeta be x.

Spend on food=1/3rdx

Spend on education=1/4x

She saves the salary=1200

x-1/3x+1/4x=1200

5x/12=1200

x=1200×12/5

x=2880

Answer 2

let Geeta's total salary is x .she spends 1/3rd of her salary on food and 1/4th on education and she saves 1200.

ATQ

$1200 + \frac{x}{3} + \frac{x}{4} = x \\1200 + \frac{4x + 3x}{12} = x \\ \frac{14400 + 7x}{12} = x \\ 14400 + 7x = 12x \\ 14400 = 12x - 7x \\ 14400 = 5x \\ 2880 = x$

hence her total salary is 2880 rs.
