A number 3257X33 is divisible by 11. Find the value of X + 3.1. 42. 13

1.	A number 3257X33 is divisible by 11. Find the value of X + 3.1. 42. 13. 34. 5
Answer» Correct Answer - Option 1 : 4 Given: 3257X33 is divisible by 11 Concept Used: A number is divisible by 11 if the difference of sum of the alternate terms is 0 or a multiple of 11. Calculations: Sum of alternate terms = (3 + 5 + X + 3) ⇒ Sum of alternate terms = (11 + X) ----(1) Sum of terms that are left = (2 + 7 + 3) ⇒ Sum of terms that are left = 12 ----(2) Difference of sum of the alternate terms is 0. (2) - (1) = 0 ⇒ 12 - (11 + X) = 0 ⇒ X = 1 Now, X + 3 = 1 + 3 ⇒ X + 3 = 4 ∴ The value of (X + 3) is 4.

Answer» Correct Answer - Option 1 : 4

Given:

3257X33 is divisible by 11

Concept Used:

A number is divisible by 11 if the difference of sum of the alternate terms is 0 or a multiple of 11.

Calculations:

Sum of alternate terms = (3 + 5 + X + 3)

⇒ Sum of alternate terms = (11 + X) ----(1)

Sum of terms that are left = (2 + 7 + 3)

⇒ Sum of terms that are left = 12 ----(2)

Difference of sum of the alternate terms is 0.

(2) - (1) = 0

⇒ 12 - (11 + X) = 0

⇒ X = 1

Now, X + 3 = 1 + 3

⇒ X + 3 = 4

∴ The value of (X + 3) is 4.
