Question

there would be 10% loss if a toy is sold at rs. 10'80 per price. at what price it be sold to earn a profit of 20%?

Answer 1

According to the question 10.80 is the 80%of original price then
90=10.80*100/x (x is the original price )
x=10.80*100/90
x=12 rs so
we need 20 %profit then
we need to calculate 120%of x
120=y*100/12 (y is the price with 20 % profit)
120*12/100=y
y=14.4rs
