Question

A shopkeeper earns a profit of Rs 1 by selling a pencil and incurs a loss of 20
paise by selling an eraser. In a given day he incures an overall loss of Rs 10 On this
day, He sold 35 pencils. How many erasers were sold by him?​

Answer 1

Answer:

225 erasers

Step-by-step explanation:

profit made by 1 pencil= Rs 1

loss made by 1 eraser = 20 paise

loss made by 5 eraser = 20 ×5 = Rs 1

now, overall loss = Rs 10

total no. of pencil sold= 35 = Rs35(profit)

thus first to equal the number the loss in terms of pencil the erasers sold would be

35 × 5=175 erasers +

an additional Rs 10 loss

10 × 5 =50

total number of erasers = 175 + 50

=225 erasers

Answer 2

Answer:

225

Step-by-step explanation:

No of pencils sold= 35

Profit earned by shopkeeper= Rs 35*1

                                                  =rs 35

Let no. of erases sold= x

Loss of shopkeeper = 20/100*x= Rs 0.2x

Total money loss /gain=Rs 10

-10=35-0.2x

x= 45/0.2

x=225

No. of erasers sold=225
