Question

A shopkeeper allows 20% discount on his goods and still earns A profit of 20% . if an article is sold for ₹360 . find the mp and cp

Answer 1

Step-by-step explanation:

SP = ₹ 360

Let MP = ₹ x

Therefore SP = MP - 20% of MP

$360 = x - \frac{20}{100} x \\ 360 = x - 0.2x \\ 360 = 0.8x \\ x = \frac{360}{0.8} = \frac{3600}{8} = 450 \\ \therefore \: MP = Rs \: 450 \: \\ Profit\: \%=\frac {SP - CP} {CP} \times 100 \\20=\frac {360 - CP} {CP} \times 100\\ 20CP=36000-100\: CP\\120CP=36000\\CP = \frac {36000} {120}\\CP= Rs 300$

Answer 2

Answer:450 and 300

Step-by-step explanation:

SP =MP (1-D/100)

= MP (1-20/100)

=4/5 MP

360×5/4=MP

450 =MP

SP=CP (1+P/100)

360=CP×6/5

360×5/6=CP

300 =CP
