The selling price is 5 and cost price is 10.Therefore there was a loss of 5 rs

Loss percentage=(5/10)*100

=50%

Total number of students is equal to 100% of the class.=500

Percentage of boys in the class=100%-36%=64%

Difference in the number of boys and girls=64%-36%=28%

Since 100%=500

28%=500*28/100=140

Since the triangles ABC and XYZ are similar therefore the ratio of their sides will be equal.

=> AB/AC=XY/XZ

=> 6/10=9/XZ

=> 3/5=9/XZ

=> 1/5=3/XZ

=> XZ=15
