Question

9. Vijay spends two-fifths of his monthly salary on food, one-tenth on the
education of his two children and one-fourth on rent. What part of his
salary is left with him?​

Answer 1

Answer:

Money spent on food=2/5

Money spent on education=1/10

Money spent on rent=1/4

Money left with him=

Salary-(Money spent on food+Money spent on education+Money spent on rent)

=1-(2/5-1/10-1/4)

=1-(15/20)

=(20-15)/20

=5/20

=1/4

Therefore, Vijay saves 1/4 part of his salary.

Answer 2

spend salary on food=2/5 × 100=40%

spend salary on children education=1/10 × 100=10%

spend salary on rent=1/4 × 100=25%

40% + 10% + 25% =75%

part of salary is left with him is = 75%
