Question

if the profit percantage is 10, the ratio of cost price and selling price is​

Answer 1

Answer:

10:11

Step-by-step explanation:

as we know

p% = profit / cp × 100

and profit = sp - cp

p% = sp - cp/cp × 100

= (sp/ cp -1)× 100

= 100sp/cp - 100 = p% = 10% ( given)

= 100 sp/cp = 110

= sp/cp = 110/100= 11/10

so cp /sp = 10:11
