Question

4. An article was sold for 300 with a profit of 25%. What
was its cost price?​

Answer 1

Answer:

Step-by-step explanation:

SP = Rs300

Profit = 25%

CP = (SP×100)/(100+profit %)

= (300×100)/(100+25)

= 30000/125

= 240

Answer 2

Required Solution:

Given:

• S.P of the article → Rs 300

• Profit % → 25%

To calculate:

• Cost price (C.P)

Calculation:

We know that,

★ $\boxed {\sf { C.P =\dfrac{100}{100+Gain\%} \times S.P}}$

$\sf { \longrightarrow C.P =\dfrac{100}{100+25} \times 300}$

$\sf { \longrightarrow C.P =\dfrac{100}{125} \times 300}$

$\sf { \longrightarrow C.P =\dfrac{100 \times 300}{125} }$

$\sf { \longrightarrow C.P =\dfrac{30000}{125} }$

$\sf \red { \longrightarrow C.P = Rs \: 240 }$

Therefore, C.P is 240.
