Question

if the selling price of 4 articles is equal to the cost price of 5 articles , find the profit per cent .​

Answer 1

Answer:

25%

Step-by-step explanation:

5 × 4 = 20

CP of 5 articles : ₹20 (say)

CP of 1 article : 20/5 = ₹4

SP of 5 articles : ₹20

SP of 1 article : 20/4 = ₹5

P = SP - CP

P = 5 - 4 = ₹1

P% = P/CP (100)

P% = 1/4(100) = 25%
