In the figure given below the triangle represents pens, the rectangle represents pencils and the circle represents erasers. Number in each area represents the number of items in that area.How many pens are pencils?
Show answer & explanation
Correct answer: C
Explanation
According to the diagrammatic representation,
Triangle = Pens
Rectangle = Pencils
Circle = Erasers
Numbers in each region represent the count of items in that overlapping area.
According to the question, we have to find pens that are pencils.
i.e. the region that overlaps between the triangle (pens) and the rectangle (pencils)
The number 5 (pens and pencils only, no erasers)
The number 16 (pens, pencils, and erasers)
So, relevant counts are 21.
Therefore, option (3) is the correct answer.
