Question

Answer 1

Answer:

Ram income increases by 24% but his expenditure increase by 12% and saving by 108% ,

his initial monthly saving = 12.5%

Step-by-step explanation:

Let say Ram Initial income = 100X

Ram Initial Saving  =  100S

Initial Expenditure = 100X - 100S

Increased Income = 100X + (24/100)100X = 124X

Increased Expenditure = 100X - 100S  + (12/100)(100X - 100S) =  112X - 112S

Increased Saving = 100S + (108/100)100S = 208S

124X = 112X - 112S + 208S

=> 12X = 96S

=> S = X/8

Initial Saving = 100 (X/8)  = 12.5X

Initial Saving % = (12.5X/100X) * 100  = 12.5 %

Initial saving = 12.5%
