find rohit's monthly salary​

Answer 1

Answer:

Rs. 60000

Explanation:

Let total amount be x

Money spent on:

Food = 1/4x

Rent = 1/3x

Other expenses = 1/15x

NGO = 1/5x

Income - Total amount spent = Remaining amount (9000)

x- (1/4x +1/3x+ 1/15x + 1/5x= 9000

x- (1/4x +1/3x+ 1/15x + 1/5x= 9000x-(17/20x)= 9000

x- (1/4x +1/3x+ 1/15x + 1/5x= 9000x-(17/20x)= 90003/20x = 9000

x- (1/4x +1/3x+ 1/15x + 1/5x= 9000x-(17/20x)= 90003/20x = 9000x= 9000×20/3

x- (1/4x +1/3x+ 1/15x + 1/5x= 9000x-(17/20x)= 90003/20x = 9000x= 9000×20/3x=60000 Answer
