a shopkeeper gains rs.1 on each pen and loses 40 paise on each pencil . he sells 45 pens and some pencils losing rs.5 in all .how much pencil does he sell.

Answer 1

Answer:

The shopkeeper sold 125 pencils.

Step-by-step explanation:

The amount of profit earned in selling 1 pen is Re. 1

The amount of profit earned in selling 45pen is Re. 1 x 45 = 45

Hence, the profit earned is Rs. 45

The net loss he suffered in selling pencil is Rs. 5.

The loss in transaction is  loss=-Rs.5 – Rs.45=-Rs.50=-5000 paise

Loss incurred in selling 1 pencil = - 40 paise

The number of pencil sold by the shopkeeper is 5000/40 = 125 pencils

Hence, the number of pencil sold by the shopkeeper is 125 pencils.

Answer 2

gains on pen =₹45*1=₹45

loss=₹5=500p

net price=45+5=50

loss in pencil=40p

number of pencil=5000p/40p
