Answer 1

$\sf\huge\underbrace{Question:}$

When oranges of ₹540 were sold, there was a loss of 10%. What is the selling price?

$\huge\sf\underbrace{Solution:}$

$\underline{\sf{\pink{ATQ,}}}$

Cost price = ₹540

Loss = 10%

Selling Price = ?

$\underline{\sf{\green{We \:know \: that}}}$

$SI= \frac{cp \times (100 - loss\%)}{100}$

By putting the values we have,

$SP = \frac{540 \times (100 - 10)}{100}$

$SP = \frac{540 \times 90}{100}$

$SP = \frac{540 \times 90}{100}$

$SP = \frac{48600}{100}$

$SP= \sf{\cancel\dfrac{48600}{100}} = 486$

∴The selling price is ₹486

$\sf\Large{\underline{\underline{Additional \: Information:-}}}$

★ The price of an item at which a shopkeeper purchases is called its cost price (C.P.) and the price at which an item is sold is known as its selling price (S.P.).

• When SP > CP , Profit is earned.

• And, When CP > SP , Loss is made.

$\underline{\sf{\pink{FORMULAS:-}}}$

Gain = SP - CP

Loss = CP - SP

Gain% = $\Large\frac{Gain}{CP}×100%$

Loss% = $\Large\frac{Loss}{CP}×100%$

★ To find S.P. when C.P. and profit or loss are given.

$SP=\large\frac{cp \times (100 - Gain\%)}{100}$

$SP=\large\frac{cp \times (100 - loss\%)}{100}$

★ To find C.P. when S.P. and profit or loss are given.

C.P. = $\large\frac{SP \times 100}{(100 + gain\%)}$

C.P. = $\large\frac{SP \times 100}{(100 - loss\%)}$

Answer 2

Step-by-step explanation:

SI = cp x (100 - loss % ) / 100

SI = 540 ( 100 - 10 ) / 100

SI = 540 x 90 / 100

SI = 48600 / 100

SI = 486.

ANS. = 486
