The width of a rectangular plot was reduced by 30% and the length was reduced by 10%. The size of the new plot is what percent of the original plot?

The width of a rectangular plot was reduced by 30% and the length was reduced by 10%. The size of the new plot is what percent of the original plot? Correct Answer 63

Let the width and length be W & L respectively. Then,  area =  W x L Width after 30% reduction = 0.7W Length after 10% reduction = 0.9L New area = 0.7W x 0.9L = 0.63 W x L (which is 63% of initial area)
