If The Number 13 * 4 Is Divisible By 6, Then * = ?

Answer»

6 = 3 x 2.

Clearly, 13 * 4 is DIVISIBLE by 2.

REPLACE * by x.

Then, (1 + 3 + x + 4) must be divisible by 3.

So, x = 1.

6 = 3 x 2.

Clearly, 13 * 4 is divisible by 2.

Replace * by x.

Then, (1 + 3 + x + 4) must be divisible by 3.

So, x = 1.
