Exercises in Retail Math 5: Calculation of CP when SP and Margin is given and Vice Versa

 Calculation of CP when SP and Margin% is given.

Remember: CP to SP, divide by 1-Margin%

You buy an item at 200 Rs with a margin of 40%, what should be the SP.

CP = \(\large{\frac{SP}{\text{(1-Margin%)}}}\)

CP = \(\large{\frac{200}{(1-0.4)}}\)

= \(\large{\frac{200}{0.6}}\)

= \(\large{\frac{2000}{6}}\)

= \(\large{\frac{1000}{3}}\)

= 333.33 Rs. 

 Calculation of CP when SP and Margin% is given.

Remember: SP to CP, Multiply by 1-Margin%

You want to sell an item at 200 Rs with a margin of 40%, what should be the CP.

CP= \({SP\times \text{(1-Margin%)}}\)

CP= \({200\times \text{(1-40%)}}\)

= \({200\times \text{60%}}\)

= 120 Rs.
