(a) What is the total number of pupils who study Twi?

a) 52
b) (a) 77
c) (a) 52
d) (a) 27

Answer 1

The total number of pupils who study Twi can be found by subtracting the number of pupils who only study Ga from the total number of pupils who study either Ga or Twi.

Step-by-step explanation:

The total number of pupils who study Twi can be found by subtracting the number of pupils who only study Ga from the total number of pupils who study either Ga or Twi. Let's denote the number of pupils who only study Ga as G, the number of pupils who only study Twi as T, and the number of pupils who study both Ga and Twi as B.

We know that 25 pupils study both Ga and Twi, so B = 25. We also know that 52 pupils study either Ga or Twi or both, so the combined total of G, T, and B is 52. Since B = 25, we can subtract this value from the total to find G + T = 52 - 25 = 27.

Therefore, the total number of pupils who study Twi (T) is 27.
