Question

I need answer for this question? ​

Answer 1

Answer:

Step-by-step explanation:

Let the number of pencils sold be x.

Shopkeeper earns profit of Rs.1 by selling 1 pen.

So, profit of pens is 45.

She also has loss of 40 paise in selling 1 pencil.

So, loss on pencil is Rs.0.4x.

Total loss value is Rs.5.

As it is loss we take -5.

So, equation would be;

45 - 0.4x = -5

45+5 = 0.4x

50 = 0.4x

50/0.4 = x

125 = x

Thus, total number of pencils sold is 125.
