Question

4. The cost price of 30 articles is equal to the selling price of 25 articles
Find the loss or gain percent​

Answer 1

Answer:

cp×30=sp×25

cp/sp=25/30

profit=5

p%=20

Answer 2

Answer:

Given in the Question :

⇒ Cost price of 30 = Selling price of 25

⇒ CP × 30 = SP × 25

• Dividing both side by 5

⇒ CP × 30/5 = SP × 25/5

⇒ CP × 6 = SP × 5

⇒ CP/SP = 5/6

⇒ CP : SP = 5 : 6

⠀⠀⠀⠀⠀───────────────

Now, Cost Price is 5 and Selling Price is 6

• Calculation of gain percent :

⇢ Gain% = Gain/CP × 100

⇢ Gain% = (SP - CP)/CP × 100

⇢ Gain% = (6 - 5)/5 × 100

⇢ Gain% = 1/5 × 100

⇢ Gain% = 20%

∴ Hence, gain percent on articles is 20%.
