Output increases from 3 units to 4 units. As a result, TC rises from `₹ 19.60` to `₹ 24.50`. Find out MC.

When output increases from 40 units to 55 units, TC increases from ₹ 2,500 to ₹ 3,250 . Calculate MC.

When output increases from 50 units to 70 units, TR increases from ₹ 4,000 to ₹ 5,000. Calculate MR.

Calculate the elasticity of supply, when price rises from ₹2 per unit to ₹3 per unit and supply rises from 20 units to 30 units.

As price of a commodity increases from ₹ 4 per unit to ₹ 5 per unit, demand falls from 20 units to 10 units. Find out the elasticity of demand.

Price of a good rises from Rs. 4 to Rs.5 per unit . As a result its demand falls from 200 units to 100 units . Calculate E_(P) .
