Question
The average income of three employees, namely Amit,
Bisht, and Cherry, is Rs. 24000. Bisht's income is 10% higher than Amit's, and Cherry's income is 50% higher than Amit's. If Cherry's expenditure is Rs. 24000, what is the amount of savings that Cherry has?Solution
ATQ, Let the income of Amit be Rs. 'a' Therefore, income of Bisht = a + 0.1a = Rs. 1.1a Income of Cherry = a + 0.5a = Rs.1.5a Sum of the incomes of all three employees = 24000 × 3 = Rs.72000 Therefore, a + 1.1a + 1.5a = 72000 Or, 3.6a = 72000 Or, a = Rs. 20000 Therefore, savings of Cherry = 1.5a – 24000 = 30000 – 24000 = Rs.6000
