$\huge\pink{\boxed{\green{\mathfrak{\overbrace{\underbrace{\fcolorbox{red}{aqua}{\underline{\pink{answer}}}}}}}}}$

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.
