Amount of Salary = Rs 18,000
(i) Total number of parts of salary = 2 + 1 + 3
= 6
Salary is divided into 3 portions as \(\frac{2}{6}\), \(\frac{1}{6}\) and \(\frac{3}{6}\)
Portion of salary used for education = \(\frac{2}{6}\)
Salary used for education = \(\frac{2}{6}\) x 18,000
= Rs 6,000
Percentage for Education = \(\frac{6000}{18000}\) x 100
= 33.33%
(ii) Usage of salary for savings = \(\frac{1}{6}\) x 18,000
= Rs 3,000
Percentage for savings = \(\frac{3000}{18000}\) x 100
= 16.67 %
(iii) Usage of salary for other expenses = \(\frac{3}{6}\) x 18,000
= Rs 9,000
Percentage for other expenses = \(\frac{9000}{18000}\) x 100
= 50 %
