A shopkeeper earns a profit of 5 by selling one note book and incurs a loss of 1 by selling an old
pen. In a particular month, the shopkeeper earns a profit of 185. If he sold 75 old pens, find the
number of the note book sold
Answers
Answer:
52 notebook
Step-by-step explanation:
Profit on one notebook=5rupees
Loss on one old pen =1 rupees
Total profit in one month= 185 rupees
Pen Solded=75
Notebook Solded=?
Loss on One Pen=1 rupees
Loss on 75Pens= 75×(-1)
=(-75)
Now,
Total Profit in one month= 185 rupees
Total Loss in one month= 75 rupees
Total Earning= 185+75rupees
= 260 rupees
so, his total earning =260 rupees
(If he earn 5 rupees by selling one notebook then how much noteboom he will sell to earn 260 rupees and for this,)
Notebook Sold= 260 rupees÷5
=52
therefore,he sold 52 notebook
( And this is the right way as my teacher told this because the question was in my previous year maths book [Wow Maths 7, Exercise 1.1, Q-10])
