Question

Sudesh sells a car to suresh at profit of 5%.and suresh sells it to ramesh at a profit of 10%.find resultant profit per percent

Answer 1

let CP = 100

profit. = 5%

:. SP. = 5%of 100+100

=5/100*100+100

=5+100

=105

this is the SP for Sudesh.

now,

CP =105

profit=10%

SP= 10%of105+105

=10/100*105+105

= 10.5+105

= 115.5

to find the profit %
