Question

2 A household Incurs a certain expenditure on the
consumption of a commodity in a given month. If
the price of the commodity is decreased by 20%
and its consumption is increased by 20%, what will
be the net percent increase or decrease in the
expenditure of the household?
1.2% 2.4% 3.8% 4.10%​

Answer 1

Answer:

Let us assume the price of the commodity is Rs 100 and you sell 100 units over a period.

The cost for them is Rs 10,000/-

When the price is reduced by 20%, it becomes Rs 80

When the consumption is increased by 20% the consumption becomes 120 units.

In the new case the cost becomes Rs 9,600/-.

The expenditure comes down by Rs 400/-
