1.	A consumer consumers only two goods X and Y whose prices are Rs 5 and Rs 4 per unit respectively. If MU_(Y) = 16 at the point of consumer's equilibrium, calculate MU_(X).
Answer» <P> Solution :A CONSUMER in consumption of two commodities is at equilibrium when, `(MU_(X))/(P_(X)) = (MU_(Y))/(P_(Y))` Putting the GIVEN values in the equilibrium condition : `(MU_(X))/(5) = (16)/(4)` `(MU_(X))/(5) = 4` `MU_(X) = 20`
