Question

Rahul saves 5% of his income. After increment his salary increases by 20% but his savings remain the same.Then calculate the increase in his expenditure​

Answer 1

Answer:

rahuls old income = X

rahul old saving = X5/100 = 0.05X

Rahul old expenditure = X - 0.05X = 0.95X

rahul new income = X20/100 = 0.2X+X

rahul s new saving is same above

so his new expenditure

= X +0.20x - 0.05x = X + 0.15x = 1.15X

rahuls expenditure increase = 1.15X - 0.95X = 0.20x
