Question

if the selling price of an orange is rupees 1.50 and there is a loss of 10% find the cost price per dozen​

Answer 1

sorry sister i am some what weak in ratios and proportion.. but i will try

cost price =x

selling price=1.50

loss=10 percent

loss=10/100×x=x/10

cost price -loss=selling price

x-x/10=1.50

10x-x/10=1.50

9x/10=1.50

x=1.50×10/9=1.66 rupees

1 dozen =12

1.66×12=19.92 rupees
