Question
Initially, Meena had a salary of Rs. 45,000 and her
expenses to savings were in the ratio 5:4. After her salary increase, she spent 10% less and saved 50% more. What was the increment in her salary?Solution
ATQ,
Initially, expenditure of Meena = 45000 × (5/9) = Rs. 25,000
Initially, savings of Meena = 45000 × (4/9) = Rs. 20,000
After salary hike, expenditure = 25000 × (90/100) = Rs. 22,500
After salary hike, savings = 20000 × (150/100) = Rs. 30,000
So, increased salary = 22500 + 30000 = Rs. 52,500
Required salary hike = 52500 – 45000 = Rs. 7,500
