This is unit elastic demand. Elasticity measures how price responds to a given variable (in this case demand). If prices and demand move at the same rate you have unit elastic demand. Mathematically it means the ratio of price change to demand change is 1.
When the percentage change in price is equal to the percentage change in quantity demanded then demand is said to be unit elastic. There are 3 kinds of price elasticity of demand.
Unit elastic
Price elasticity of demand= percentage change in demand/percentage cgange in price 2 = % chnge in demand/10 % change in demand= 2*10 % change in demand= 20%
a change in demand is a movement along the demand curve, and a change in quantity demanded is a shift in the demand curve
Change in demand is subjective, it could be increase or decrease in the qauntity of good or services asked for, while change in quantity demand is objective, it refers to actual quantity/amount of good or seevices requested /demanded .

perfectly elastic demand the quantity change by infinitely large amount proportion due to the small change in price, is called perfectly elastic demand. perfectly inelastic demand the quantity demand doesn't change at all due to the change in price is called perfectly inelastic demand. relatively elastic demand the quantity demand changes by a little more percentage than the change in price is called relatively elastic demand. relatively inelastic demand the percentage change in quantity demand is less than the percentage change change in its price is called relatively inelastic demand unitary elastic demand the percentage change in quantity demand is equal to the percentage change in price is called unitary elastic demand

A change in quantity demanded
change in life style also causes change in quantity demand for eg: in 1960's formal wear were in demand but with change in style nowadays denim wear in demand.
