I have added the complete question in the attachment

15

Step-by-step explanation:

From the diagram in the attachment

27⁰ represents 3 pupils they love PE

135⁰ represents those that love mathematics. But the number was not given.

We have;

27⁰ = 3

135⁰ = ?

We cross multiply to find the unknown

135⁰x3 = 27⁰?

405 = 27⁰?

Divide through by 27

405/27 = ?

15 = ?

Therefore 15 pupils said mathematics was there favorite
