Question

(OR)
Arun sold two Bicycles at Rs. 3600 each. He got 20% profit on first
bicycle and 20% loss on second bicycle. Find his total profit or loss.​

Answer 1

Step-by-step explanation:

If it's Profit,

$\bold{\underline{\underline{Formula\: :}}}$

$C.P\:=\: \Large{\frac{100}{100\:+\:P}}$ ${×\:SP}$

= $\Large{\frac{100}{120}}$ ${×\:3600}$

$\boxed{CP\:=\:3000}$

If it's loss,

$\bold{\underline{\underline{Formula\: :}}}$

$C.P\:=\: \Large{\frac{100}{100\:-\:L}}$ ${×\:SP}$

= $\Large{\frac{100}{80}}$ ${×\:3600}$

${\boxed{CP\:=\:4500}}$

Now,

Total cost price = 4500 + 3000 = ₹7500

Total selling price = 3600 + 3600 = ₹7200

CP > SP so, it's loss of ₹300

Loss% = $\Large{\frac{Loss}{CP}}$ ${×\:100}$

= $\Large{\frac{300}{7500}}$ ${×\:100}$

Loss% = $\large{\boxed{4\:percent}}$
