# QA – Placement Quizzes | Percentages | Question 4

Jack consumes 75% of his salary. Later his salary is increased by 20% and he increases his expenditures by 10%. Find the percentage increase in his savings.**(A)** 51%**(B)** 60%**(C)** 50%**(D)** 55%**Answer:** **(C)****Explanation:** Let Jack’s original salary be Rs 100. Then,

his expenditure = Rs 75,

his savings = Rs 25.

Now, his new salary = Rs 120. So,

new expenditure = (110/100) × 75 = Rs 165/2,

new savings = 120 – 165/2 = Rs 75/2.

Increase in savings = 75/2 – 25 = Rs 25/2.

Therefore, percentage increase in savings = (25/2)/25 × 100% = 50%.
