why does indifference curve does not intersect each other?

Answer 1

it is simple for eg thee are two ic curve i1 n i2 n i1 is above i2 n there are points an b in i1 n i2 resp ....
n c is the intrsection point of 2 curves so we can say that a consumer is indifferent to point b n c as they lie on same curve .similarly consumer is also indifferent to point
a n c. thus it means he is indifferent to point a n b which violates the 1st ssumption of ic curves that
consumer prefer to be on a large ic curve rather thn a lower one.........

Answer 2

Indifference curves are a way of showing a 3 dimensional shape in 2 dimensions. The utility function U(x,y) is like a hill where the more satisfied you are the higher you are on the hill . Indifference curves are the x y coordinates of a line of constant height (satisfaction). The same x,y coordinates can not be at 2 heights nor can they represents 2 levels of satisfaction.

Answer 3

INDIFFERENCE CURVES REFLECT UNIQUE LEVELS OF UTILITY. HENCE THEY DONOT INTERSECT FOR OTHERWISE TWO CURVES WOULD REPRESENT THE SAME LEVEL OF UTILITY - AN ABSURD PROPOSITION!
