Question

A shopkeeper gains 1 on each pen and loss 40 paise on each pencil. He sells 45 pens and some
pencils. If the losing Rs 5 in all, then how many pencils does he sell?
​

Answer 1

Answer:

125

Step-by-step explanation:

He sold 45 pens

Profit = 45 × 1 = 45 Rs

But his net is 5 Rs loss

So,

his loss in selling pencils = 50 Rs

Loss/pencil = .04 RS

Number of pencils = 50/0.4 = 500/4 = 125

Answer 2

Answer:

125

Step-by-step explanation:

let he sells x pencils.

Total loss(on pencils) = 40x paise

Total gain(on pens) = 100x45 = 4500 paise

net loss is given as Rs.5/- = 500 paise

40x 4500 500

40x = 5000

x = 5000/40

x = 125 pencils
