Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 35.5%.

Savings of Ramesh in initial year = 16500 - 10500 = Rs. 6000

Saving% = (6000/16500) × 100 = 36.36%

Increase in income from next year,

⇒ Increased income = 16500(1 + 25%)

⇒ Increased income = 16500(1 + 1/4)

⇒ Increased income = 16500 × 5/4

⇒ Increased income = Rs. 20625

Increase in expenses from next year,

⇒ Increased expense = 10500(1 + 19/100)

⇒ Increased expense = 10500(1 + 0.19)

⇒ Increased expense = 10500 × 1.19

⇒ Increased expense = Rs. 12495

Savings from next year,

Savings = 20625 - 12495 = Rs. 8130

The total increase in savings,

⇒ Savings% = [(8130/6000) - 1] × 100

⇒ Savings% = [(8130 - 6000)/6000] × 100

⇒ Savings% = 2130/6000 × 100

⇒ Savings% = 35.5%
