Question

by selling an article for rupees 3600 mm and makes a profit of 20% what is the cost price of the article what would his gain percent be if he sold the article for rupees 4000

Answer 1

Here CP = 100%
profit = 20%
SP = CP + Profit
120% = 3600
1 % = 30
100 % = 3000
Rs 3000 is CP

Now if SP = Rs 4000
then profit = 4000-3000 = 1000
profit % =
$\frac{1000}{3000} \times 100$

= 33.33%

Answer 2

Heya...
Here is your answer ---

=> Selling Price (SP) = ₹ 3600

=> Profit = 20%

=> Cost Price (CP) = 100/(100 + G%) × SP

=> Cost Price (CP) = 100/(100+20) × 3600

=> Cost Price (CP) = 100/120 × 3600

=> Cost Price (CP) = 100/12 × 360

=> Cost Price (CP) = 100 × 30

=> Cost Price (CP) = ₹ 3000

Now, Selling Price (SP) = ₹4000

=> Gain = SP - CP

=> Gain = ₹ (4000 - 3000)

=> Gain = ₹ 1000

=> Gain% = Gain/CP × 100

=> Gain% = 1000/3000 × 100

=> Gain% = 1/3 × 100

=> Gain% = 33 1/3 % = 33.3 %
