Question:

The sum of two numbers x and y is 48 and their difference is 6. Then x : y = ?

Options:

8 : 9

7 : 6

9 : 7

3 : 7

Correct Answer:

9 : 7

Explanation:

Here,

x + y = 48  ..(1.)

x - y =  6    ..(2.)

2x   =  54

⇒ x = 27,

Putting in (1.)

⇒ 27 + y = 48

⇒ y = 48 - 27

⇒ y = 21,

Ratio of x and y = 27 : 21 = 9 : 7.
