What is the total number of students attending classes at Apti4All?
Explanation:
From the given data, we get the following diagram.
∴ Number of students studying only QA = 108 – (10 + 20 + 14 + 16 + 24) = 24.
∴ Number of students studying only DILR = 80 – (14 + 16 + 24 + 14) = 12.
∴ Number of students studying only VA = 72 – (10 + 16) = 46.
∴ Number of students studying only RC = 98 – (20 + 24 + 14) = 40.
Hence, we get the final diagram.
∴ The total number of students at Apti4All = 24 + 10 + 20 + 14 + 16 + 24 + 12 + 14 + 46 + 40 = 220.
Hence, 220.
