Answer:

Step-by-step explanation:

Given,

The number of pens in a box decreased from 20 to 10

To find,

The percentage decrease in the number of pens

Assumption,

Let Initially, the total number of pens in a box be 'N'.

Let the decrease in no. of pens in a box be 'n'.

Calculation,

Initially, the total number of pens in a box is (N) = 20

The decrease in no. of pens in a box is 20 - 10 (n) = 10

Hence, % decrease of pens in a box is n/N × 100

⇒ 10/20 × 100%

⇒ 50 %

Therefore, the percentage decrease in the number of pens is 50 %.
