Question

Print price of an article is 25% more than its cost price. At what
percent less should it be sold for no profit and no loss?​

Answer 1

Answer:

20%

Step-by-step explanation:

Successive discount formula =  ( x + y + xy / 100 ) %

We know X = 25%

Overall change in value to be 0 as there is no need of profit or loss.

As we have look for how much discount to be given we consider Y to be negative value.

Therefore,

X + (-Y) + ((X * -Y)/100) = 0

25 - Y - (25 * Y)/100 = 0

25 - Y - Y/4 = 0

25 = Y/4 + Y

25 = 5Y/4

Y = 20%

Answer 2

Answer:20%

Step-by-step explanation:

Let cost price cp=100.

(cp of 100 is 100% )

100=125% (25% more than the cp)

? =100% (100% for no profit no loss)

100/?=125%/100%

(percentages canceled on right side)

( cancle 25 table in right side)

100/?=5/4

400=? (5)

80 =? (cp of 80 is 80%)

Cp 100%-80% is 20%
