Question

Pihu is counting the number of equipments being used in making the chocolate cake.


Identify the first number by filling the missing digits.

• A. $422,542$
• B. $421,592$
• C. $429,552$
• D. $420,582$

Answer 1

The correct option is C $429,552$

In the given question, few digits of a number are missing.


We have to perform addition and subtraction simultaneously to identify the correct number.


So $2+9=11$. We regroup it as 1 Ten and 1 Ones.

We can observe that $1+5+6=12$. We regroup it as 1 Hundred and 2 Tens.

So, the first missing digit from the right is 5.

Continuing in this process, we get:
$1+5+3=9$

$9+1=10$

So, the second missing digit from the right is 9.

And, $1+2+6=9$

Finally, $4$ will be brought down as it is.

Hence, the first number used here is $429,552$
