Solution

The correct option is C 1 sharpner,
4 pencils,
3 erasers
To find the highest number of each item one pencil box can contain, we need to find the HCF of the 3 given numbers and pick the corresponding left over factor at the end.

238,152,1141919, 76,57 1, 4, 3

Since there are no common factors for 1, 4 and 3 we cannot factorise it further.

The last row indicates the number of each corresponding item in one box.

Hence there will be 1 sharpner, 4 pencils and 2 erasers in each pencil box.
