In a science test. Devi scores 16 marks more than Ali. lf

sergeinik [125]

Let the marks of Devi be x and Ali be y.

So, the equations:

2y = x <em>and</em> y + 16 = x

So,

2y = y + 16. [ because we know equals are equal to equals]

=> 2y - y = 16

=> y = 16

Check

Ali's marks are half of Devi's marks.

Devi's marks are 16 more than alis.

So, Devi's marks will be 16×2 = 32 and 32 is 16 greater than 16 (16+16=32).
