Question

10. the number 237* is divisible by 3 then the unknown non-zerodigit marked as * will be

1)1 2)4

3)6 4)5



plz answer

Answer 1

Answer:

3) 6.

Step-by-step explanation:

The sum of all the digits in a given number should be divisible by 3.

237* , then the sum of the three numbers i.e. 2 + 3 + 7 = 12. 12 + 6 = 18. 18 is divisible by 3.

I hope you understand this answer to you.

The number 237* is divisible by 3 then the unknown non- zero digit marked as * will be

(i) 1

(ii) 4

(iii) 6

(iv) 5

$\huge{\underline{\mathtt{\red{A} \pink{N} \green{S} \blue{W} \purple{E} \orange{R}}}}$

$\sf\green{Given :}$

➣ The Number 237* is divisible by 3

➣ The unknown digit is a non - zero digit

$\sf\pink{To\: Find :}$

➣ The Unknown non - zero digit marked as *

$\sf\red{Solution :}$

➪ Divisibility Rule of 3 = Sum of Digits should be divisible by 3

⇒ $\frac{2 + 3 + 7 + * } {3}$

⇒ $\frac{12 + * } {3}$

➦ 12 is completely divisible by 3 but * is a non - zero digit so the value of * cannot be 0.

$\:$

➤ If we add 1 to 12 then we get = 12 + 1 = 13

13 is not divisible by 3

So, option (i) is not correct.

$\:$

➤ If we add 4 to 12 then we get = 12 + 4 = 16

16 is not Divisible by 3

So, option (ii) is not correct.

$\:$

➤ If we add 6 to 12 then we get = 12 + 6 = 18

18 is completely Divisible by 3

So, option (iii) is correct.

$\:$

➤ If we add 5 to 12 then we get = 12 + 5 = 17

17 is not Divisible by 3

So, option (iv) is not correct.

➙ $\sf\orange {So,\: the\: correct\: answer\: is\: option (iv)}$
