Solution

## The correct option is B 18No. 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. ∵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.
