(12345679 x 72) = ?

= 12345679 x 70 + 12345679 x 2

= 864197530 + 24691358

= 888888888

If the product 4864 x 9 P 2 is divisible by 12, then the value of P is:

So, 9P2 must be divisible by 3.

So, (9 + P + 2) must be divisible by 3.

P = 1.

-84 x 29 + 365 = ?

= -(84 x 30) + 84 + 365

= -2520 + 449

= -2071

If the number 97215 * 6 is completely divisible by 11, then the smallest whole number in place of * will be:

(6 + 5 + 2 + 9) - (x + 1 + 7) = (14 - x), which must be divisible by 11.

x = 3

If the number 5 * 2 is divisible by 6, then * = ?

Then, (5 + x + 2) must be divisible by 3. So, x = 2.
