Question

The average of marks in 3 subjects is 224. The first subject marks is twice the second and the second subject marks is twice the third. Find the second subject marks ?

Answer 1

Let the third subject marks = w

=> Second subject marks = 2w

=> First subject marks = 4w

now,

$\frac{w +2w +4w }{2} = 224 \\ \\ = > 7w = 448 \\ \\ = > w = 64$

So,

Subject 1 marks = 4w = 256

subject 2 marks = 2w = 128

Subject 3 marks = w = 64
