Varun’s monthly expenditure is Rs 4,000 less than Aman’s monthly expenditure. Varun’s monthly saving is 50% less than Aman’s monthly saving. Find the difference between their annual salaries.

ATQ, Aman’s monthly salary is 60% more than Varun’s monthly salary. So, Aman’s salary : Varun’s salary = 160 : 100 = 8 : 5 Let Aman’s monthly salary = 8x and Varun’s monthly salary = 5x. Average monthly expenditure = Rs 26,000 So, total monthly expenditure = 26000 × 2 = Rs 52,000 Let Aman’s expenditure = e. Then Varun’s expenditure = e − 4000. So, e + (e − 4000) = 52000 2e − 4000 = 52000 2e = 56000 e = 28000 Aman’s monthly expenditure = Rs 28,000 Varun’s monthly expenditure = 28000 − 4000 = Rs 24,000 Aman’s monthly saving = 8x − 28000 Varun’s monthly saving = 5x − 24000 Varun’s saving is 50% less than Aman’s saving. So, Varun’s saving = 50% of Aman’s saving = 1/2 of Aman’s saving. 5x − 24000 = 1/2 × (8x − 28000) Cross multiply: 2 × (5x − 24000) = 8x − 28000 10x − 48000 = 8x − 28000 10x − 8x = 48000 − 28000 2x = 20000 x = 10000 Difference between monthly salaries = 8x − 5x = 3x = 3 × 10000 = Rs 30,000 Difference between annual salaries = 30000 × 12 = Rs 3,60,000
