Correct Answer - Option 2 : 20000
Given:
His saving = 40% of his monthly salary
Total expenditure = 15% of monthly salary + 10% of monthly salary + 7000
Calculation:
Let be assume his monthly salary is p
Expenditure of A = (60/100) × p
⇒ (3/5) × p = (15/100)p + (10/100)p + 7000
⇒ p = 20000
∴ The monthly salary of A is 20000.
