Question

a man spends 2/5 of his salary on house rent, 3/10 of his salary on conveyance. if he has Rs.1400 left with him, find his expenditure on food and conveyance?

Answer 1

Step-by-step explanation:

let his salary be x rs

now on rent he spent= 2x/5

and on conveyance =3x/10

and saved 1400 rs

so 2x/5 +3x/10 =x including saving

7x /10 x=7/10+3/10 saving

expenses 7/10 saving 3/10

3/10 is equal to 1400 rs

so x=4666

spent on rent 2×4667/5=1866 rs and on conveyance 3×4667/10=1400

1400+1400+1866=4666
