Sumit spends 15% of his monthly salary on rent 20% of remaining on tax and 8% of total salary on transport and 25% of remaining on other expenditure remaining amount he saved which is 90000 then find the annual income of sumit. Correct Answer 2400000
Solution:
Given:
Sumit spent on rent is = 15% of his monthly salary
Sumit spent on tax is = 20% of remaining salary
Sumit spent on transport = 8% of monthly salary
Sumit spent on other expenditure = 25% of remaining
Sumit saving is = 90000
Concept: A% = A/100
Let be assume sumit total monthly salary is = B
Now,
⇒ (15/100) × B + (20/100) × (85/100) × B + (8/100) × B + (25/100) × 60/100 × B = (55/100) × B
⇒ Then saving will be (45/100) × B = 90000
⇒ B = 20,0000 this is monthly salary of sumit we have to find his annual salary which is
⇒ 12 × B = 12 × 20,0000 = 24,00,000
∴ 24,00,000 would be correct answer.
