Question

Ritu sells a pen for rupees 63 and loses 1/10 of her outlay. Find (1) cost price of the pen (2) loss percent​

Answer 1

Answer:

let the cost of pen be x

1/10 of x= x - 63

63=9/10 of x

63*10/9=x

70=x

Therefore the cost of pen is ₹70

loss percent=(CP-SP)*100/CP

=(70-63)*100/70

=700/70

=10%

therefore Ritu had 10% loss
