Question

Why can two indifference curves not intersect each other?

Answer 1

Answer:

The indifference curves cannot intersect each other. It is because at the point of tangency, the higher curve will give as much as of the two commodities as is given by the lower indifference curve. ... Similarly the combinations shows by points B and E on indifference curve IC1 give equal satisfaction top the consumer

Answer 2

Answer:

Two indifference curves cannot intersect each other because, two indifference curves cannot have the same level of satisfaction to the consumer.

Say a point A on IC1 and IC2, IC1 being AC IC2 being AB Now A = B and A = C, so that must imply B = C but thats not the case because its against the basic assumption of an indifference curve.
