Question

5∆3 = 18
4

3∆5 = 65
3

9∆6 = ?
3
​

Answer 1

Let us get a logic from the problems first:

1st one.

5 | 3 | 4 = 18

>> 5 + 3 + 4 + 1 + 8 = 21

2nd one.

3 | 5 | 3 = 65

>> 3 + 5 + 3 + 6 + 5 = 22

We can see that the digits are added one by one.

From the first two numbers, we can say that the next sum must be 23.

3rd one.

9 | 6 | 3 = ??

>> 9 + 6 + 3 + ? + ? = 23

>> 18 + ? + ? = 23

>> ? + ? = 5

The sum of the digits of the required number must be equal to 5.

From the given option, we can say that, 50 is the only number given whose sum of the digits is 5.

Therefore, 9 | 6 | 3 = 50
