Question

Given below is the detail of total number of food tokens.


Identify the second number by filling the missing digits.

• A. 2,496
• B. 2,595
• C. 2,396
• D. 2,696

Answer 1

The correct option is C 2,396

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


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


Only addition of 6 with 6 gives 12, or 6 + 6 = 12.
∴ The first missing digit from the right is 6.
We regroup 12 as 1 ten and 2 ones.

In the second step, 1 + 5 + 9 = 15.
We regroup it as 1 hundred and 5 tens.

Continuing in the same process, for the third step, we get:
1 + 4 + 3 = 8
∴ The second missing digit from the left is 3.

Finally, 8 + 2 = 10

Hence, the correct second number which is added is 2,396.
