Question

In a month a man spent 40% of his income on food, 15% on education, 10% on transport, 15% on entertainment and 5% on miscellaneous expenditure
and saved the rest. If his savings is Rs. 4500, find his
a) Monthly salary
b) amount spent on food
c) amount spent on
education.​

Answer 1

(a)  Let the salary be x Spent on food =2x/5

Spent on education =3x/20

Spent on transport =x/10

Spent on entertainment =3x/20

Spent on miscellaneous expenses =x/20

Savings =4500 x=2x/5+3x/20+x/10+3x/20+x/20+4500

On solving  3x=90000 x=30000 is the monthly salary  

b)  Spent on food =2/5*30000 =12000

Spent on transport =30000/10 =3000

Spent on education =3/20*30000 =4500
