Question

A shopkeeper earns a profit of ₹2 by selling one marker pen and incurs a loss of ₹1 per eraser. 1. In the month of January, he incurs a loss of ₹5. In that month, he sold 40 marker pens. How many erasers did he sell in the month of January? 2. In the next month, he earns neither a profit nor a loss. If he sold 65 marker pens, how many erasers did he sell?

Answer 1

Answer:

1. In the month of January he sold 5 erasers.

2. In the next month he sold 65 erasers.

Step-by-step explanation:

1. In January he incurs a loss of Rs.5

Loss incurs in 1 eraser - Rs. 1

Loss incurs in 5 eraser - Rs. 5

2. In next month he sold marker pens - 65

Profit incurs - 65*2 - 130

How much loss he incurs so neither loss nor profit - 1/2 of 130 - 65

So, he sold 65 erasers in next month

Answer 2

Answer:

Profit earned per marker pen = ₹ 2

Loss incurred per eraser = ₹ 1

Step-by-step explanation:

1.

Loss incurred = ₹ 5

Marker pen sold = 40

Eraser sold = 2/1 * 40 = 80 + 5 = 85

Ans. He sold 85 erasers in the month of January

2.

Marker pen sold in the next month = 65

Erasers sold in the next month = 2/1 * 65 = 130

Ans. He sold 130 erasers in the next month
