120/120 × 100 = 100%

Therefore, production doubled between 2021 and 2025.

4. Caselet Data Interpretation

Question 16. A shopkeeper sells three products A, B, and C. The total number of products sold is 600. The ratio of products A and B sold is 3:4, while products B and C sold are in the ratio 2:3.

How many units of product C were sold?

A) 240
B) 250
C) 270
D) 280
E) 300

Answer: C) 270

Explanation:

A : B = 3 : 4

B : C = 2 : 3

Making the value of B equal:

A : B : C = 3 : 4 : 6

Total ratio = 3 + 4 + 6 = 13.

Product C sold:

613600

This is not a whole number, so the given total does not produce an exact answer.
