Question
Roja earned ₹ 18,000 per month. She utilized her salary in the ratio 2 : 1 : 3 for education, savings and other expenses respectively. Express her usage of income in percentage
Solution
Amount of Salary = ₹ 18,000
(i) Total number of parts of salary = 2 + 1 + 3 = 6
Salary is divided into 3 portions as `2/6, 1/6 and 3/6`
Portion of salary used for education = `2/6`
Salary used for education = `2/6 xx 18,000` = ₹ 6,000
Percentage for Education = `6000/18000 xx 100` = 33.33%
(ii) Usage of salary for savings = `1/6 xx 18,000` = ₹ 3,000
Percentage for savings = `3000/18000 xx 100` = 16.67%
(iii) Usage of salary for other expenses = `3/6 xx 18,000` = ₹ 9,000
Percentage for other expenses = `9000/18000 xx 100` = 50%
