Question

A shopkeeper earns a profit of 5 by selling one note book and incurs a loss of 1 by seeling 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 books sold.​

Answer 1

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

Do as same as this
