Answer:
Hi friends
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:)

Step-by-step explanation:
Profit per pen = re.1
profit for 45 pens = rs.45
if profit is always in positive then loss for the month is -5
so 45+x = -5
x = -50
so the loss is -50
pencils sold = (50/0.40)
= 125
