Question

2. 83:55 :: 65 : ?
(a) 8
(c) 13
(b) 11
(d) 15​

Answer 1

Answer:

Option (b), 11 is correct

83 : 55 :: 65 : 11

Step-by-step explanation:

The first ratio = 83 : 55

How we obtain it?

Here 83 = (8 + 3) * (8 - 3)

= 11 * 5 = 55

We see that the ratio 83 : 55 is obtained for second term 55 by finding the product of of the sum of the digits of 83 and the difference of the digits of 83.

Then 65 = (6 + 5) * (6 - 5)

= 11 * 1 = 11

Therefore the second ratio is

= 65 : 11
