O relatively responsive to a change in price. O relatively unresponsive to a change in price. O completely responsive to a change in price. O unaffected by a change in price.Explanation / Answer
1)
Right answer is : 50 Percent .
Since the value of income elasticity is 5 which means 1 percent change in income will lead to change in demand by 5 %. Thus, 10 % change in income would cause 50 % change in demand.
2)
Right answer is : completely responsive to change in price.
Elastic demand means elasticity of demand which is greater than one.
3)
Right answer is : Luxury; Necessity.
Since in first case income elasticity of income is very higher, thus is luxury and in second case, consumer is relatively less sensitive change in income, thus it is necessity.
