15 for 20. He mixed them and sells at 20 for 20. Find the gain or loss per cent in the transaction.
ul number of pens for 2.25 each. If he sells both at
pay for his book?​

Answer 1

Step-by-step explanation:

If you notice the question, (assume the man purchases 100 oranges of each variety):

He can buy 25 oranges of variety 1 for 1 rupee.Therefore for 100 oranges he pays (100/25)*1 =4 rupees

He can buy 20 oranges of variety 2 for 1 rupee.Therefore for 100 oranges he pays (100/20)*1 =5 rupees

Now he has 100+100 =200 oranges which cost him 4+5=9 rupees which is his Cost Price CP.

Now he mixes them and sell them as 45 oranges for 2 rupees until he sells 200 oranges.

So he gains money = (200/45)*2=8.88 rupees which is his selling price SP, which is less than his CP.

Therefore he experiences a loss of CP-SP =9–8.88=.1111 rupees

loss %=(.1111/9)*100 = 1.23% Loss approx:)
