Answer 2

✯Given :-

➝ 24a is a multiple of 9

✯To find :-

➝ The value of a

✯Solution :-

➜ We know that, a number is divisible by 9 if the sum of it's all the digits is a multiple of 9 (Divisibility rule of the number 9)

➜ Let the required number be x

➜ According to the question,

➙24a = 9x

➙2 + 4 + a = 9x

➙6 + a = 9x

➙x = 6 + a ÷ 9

➙x is a multiple of 9

➞ If a = 0, then ⁶⁄₉ is not divisible by 9

➞ If a = 8, then ¹⁴⁄₉ is not divisible by 9

➞ If a = 9, then ¹⁵⁄₉ is not divisible by 9

➞ If a = 3, then ⁹⁄₉ is Divisible by the number 9

✣ The value of a is 3 and the least value, which is possible for a is 3 ✣
