Question [24]:— If 213 × 27 is divisible by 9 where x is a digit , what is the value of x ?

Answer:—

• False

Explanation:

If 213 x 27 is divisible by 9, then the sum of the digits of a number is a multiple of 9.

• 2 + 1 + 3 + x + 2 + 7 = 15 + x

Then 15x must be any multiple of 9 such as 9, 18, 27 …

Now assume that,

→ 15+x = 18

→ x = 18 - 15

→ x = 3

Question [25]:— Simplify:— 5/4 + (-3/8) + 1/2 + (-7/4)
