Answer: 12.5 % increase in consumption. Step-by-step explanation: Assume 100 units price as Rs. 100. 1. Since price decrease by 20 % ( 1/5 ) , consumption increases by 25% (1/4).(#using price 1 x cons 1 = price 2 x cons 2 ) 2. Therefore, consumption is now 125 units whose price is 125 Rs. 3. Now varun wants to spend 10 % less . i.e; 10% of 125 = 12.5 less Therefore he wants to spend 112.5 Rs. That means he must consume 112.5 units. 4. Therefore it is 12.5 % more than 100 . Reply

Assume 100 units price as Rs. 100.
1. Since price decrease by 20 % ( 1/5 ) , consumption increases by 25% (1/4).(#using price 1 x cons 1 = price 2 x cons 2 )
2. Therefore, consumption is now 125 units whose price is 125 Rs.
3. Now varun wants to spend 10 % less . i.e; 10% of 125 = 12.5 less
Therefore he wants to spend 112.5 Rs. That means he must consume 112.5 units.
