GIVEN :

A MAN SPENDS :

=> 2/5 OF SALARY ON HOUSE RENT

=> 3/10 OF SALARY ON FOOD

=> 1/8 OF SALARY ON CONVEYANCE

AND REMAINING SALARY IS RS 140

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

LET ,

=> SALARY OF MAN = 40X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

EXPENDITURE OF THAT MAN :

=> 2/5 OF 40X ON HOUSE RENT

=> 3/10 OF 40X ON FOOD

=> 1/8 OF 40 X ON CONVEYANCE

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

✓ 2/5 * 40X

=> 16X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

✓ 3/10 * 40X

=> 12X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

✓ 1/8 * 40X

=> 5X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

16X + 12X + 5X

=> 33X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

HE IS LEFT WITH :

=> TOTAL SALARY - EXPENDITURES

=> 40X - 33X

=> 7X

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

BUT WE HAVE GIVEN THE REMAINING AMOUNT :

SO,

=> 140 RS = 7X

=> X = 140 / 7

=> X = 20

⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕⭕

HIS SALARY = 40X

=> SALARY = 40 * 20

=> SALARY = 800 rs
