Question

9 : 17 :: 8 : ?
options
32
19
40
23
..
...with explain concepts​

Answer 1

The correct form should be:

9 : 17 :: 8 : 23.

* The logic followed in the case of the first set of numbers should be followed in the next set as well.

* As observed 9 and 17 are related as:

(9*2)-1 = 17.

* In case of the second one,( 8*2)-1 is 15 but there's no such option present so we try the next possibility.

* We find that (8*3)-1 is 23 and this satisfies the condition and is also present as an option.

Answer 2

Answer:9:17::8:23

Explanation:(9×2)-1=17

(8×2)-1=15 But there's no option present.

So, (8×3)-1=23

* We find that (8*3)-1 is 23 and this satisfies the condition and is also present as an option. {Thank you :) }
