Question

A laborer earns ₹ 200 per day and spends 80% of his daily earning. Calculate his savings in the year 2010.

Answer 1

Answer:

Let income of person = Rs. 100

Spent on different expenses = Rs. 60

Savings = Rs. 100 - Rs. 60 = Rs. 40

Now, income after increment of 20 % = 100+

100

20

×100=Rs.120

Expenses after increment of 10 % = 84 Rs.

New saving = 120-84= Rs. 36

Now, percentage of decrease in savings = (

40

40−36

)×100=10 %
