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
