Answer:
A shopkeeper earns a profit of rs 5 by selling one notebook and incurs a loss of rs 1 by selling an old pen. In a particular month the shopkeeper earns a profit of rs 185 . If he sold 75 pens, find the number of the notebook sold .
Step-by-step explanation:
SOLUTION :
amount of profit he gets for the notebook = 5 rps
amount of loss he gets for the old pen = 1 rps
Now, the amount of pens = 75
Amount of profit he gets in a particular month =185 rps
Total amount of note books= ( linear equation)
let x be the amount =x - 75 = 185
x=185+75
x= 260
now we have to divide it by 5
=5\260
=52
there is your answer:)
Answer:
Profit from notebook = ₹5
loss from old pens = ₹1
He sold pens in a month = 75
His profit = ₹185
let x be the number of books
=75-x = 185
=x=185-75=
260
260÷5
= 52
