Best answer
Correct Answer - Option 1 : 110/3%

Given:

The monthly income increased by 25%

Calculation:

Let the monthly income of Akash be 100 rupees initially

⇒ The initial expenditure of Akash = 70

⇒ Initial saving of Akash = 30

⇒ Final monthly income of Akash = 125

⇒ Final expenditure of Akash = 84

⇒ Final saving of Akash = 41

⇒ percentage increase his saving = (41 - 30)/30 × (100) = 11/30 × (100) = 110/3%

∴ The required result will be 110/3%.
