Question

A person spends 70% of its income. His income increased by 25% and his expenditure was increased by 10%, how many% increase in his savings?

Answer 1

Answer:

15%x

Step-by-step explanation:

Income=x (let)

Initially,

Expenditure=70%x

Savings=30%x

Finally,

Income=x+25%x

Expenditure=(70%+10%)x=80%x

Savings=x+25%x-80%x

=x-55%x

=45%x

Increase in savings=45%x-30%x

=15%x
