Question

2222+99+9+AAA=299A find the missing digits

Answer 1

Here A=7..............

Answer 2

Answer: The missing number is 6.

Step-by-step explanation:

Since, a number can be written as the sum of the place value of all of its digit.

That is, we can write,

AAA = 100 A + 10 A + A

And, 299A = 2000 + 900 + 90 + A.

Here, the given expression,

2222 + 99 + 9 + AAA = 299A

⇒ 2222 + 99 + 9 + 100 A + 10 A + A = 2000 + 900 + 90 + A

⇒ 2330 + 111 A = 2990 + A

⇒ 111 A - A = 2990 - 2230

⇒ 110 A = 660

⇒ A = 6

Hence, the value of A is 6.
