Question

Joey has $26$ erasers with him. If he gave $8$ erasers to his sister, then how many erasers are left with him $?$

• A. $28$
• B. $18$
• C. $12$
• D. $28$

Answer 1

The correct option is B $18$

No. of erasers Peter have $=26$

No. of erasers he gave it to her sister $=8$

Number of erasers remaining with him $=26-8$.

To subtract these numbers, we first align them according to Place Value table.

Now, as subtracting numbers of Ones place, we get

$6-8$, which is not possible.

$\because 1$ Tens $=10$ Ones

$2$ Tens $=1$ Tens $+10$ Ones

Therefore, for subtracting Digits at Ones place, we will borrow $1$ Tens(or 10 Ones) from $2$ Tens.

So, digit at Ones place will become $16$.

At tens place $1-0=1$


Therefore, number of erasers remaining with him $=18$.
