Solve the Math Puzzle: Solution

In the picture, we see that,

JAPAN = 15

POLAND = 24

AUSTRIA = 35

SINGAPORE = ??

Now, the logic is that JAPAN has 5 letters, so the value is 5, and when multiplied by 3, it becomes 15.

Similarly, the following country is POLAND, with 6 letters; as the number of letters increases by 1, we will multiply by a number greater than the previous one.

Therefore, POLAND will be multiplied by 4, and it becomes 6 * 4 = 24

Now, applying the same logic, we get SINGAPORE's value as 48.

SINGAPORE = 8 ( 8 letters)

Multiplied by 6 

8 * 6 = 48
