The correct option is
B 4 boxes
Total number of paint bottles
=1769
Now,
1769 paint bottles can be divided eqaully into any one of the following:
3 boxes,
4 boxes,
5 boxes or
6 boxes
The number of paint bottles left outside in each case is the remainder obtained by calculating
1769÷Number of boxes
Look for the least remainder.
So, if the bottles are packed equally into
3 boxes, calculate the remainder for
1769÷3
Calculating
1769÷3 by standard algorithm,
So, the remainder of
1769÷3 is
2
∴ If
1769 paint bottles are equally packed into
3 boxes,
2 bottles will remain outside the boxes.
Next, calculate the case in which the paint bottles are packed equally into
4 boxes.
Calculating
1769÷4 by standard algorithm,
So, the remainder of
1769÷4 is
1.
∴ If
1769 paint bottles are equally packed into
4 boxes,
1 bottle will remain outside the boxes.
Next, calculate the case where the paint bottles are equally packed into
5 boxes.
Calculating
1769÷5 by standard algorithm,
So, the remainder of
1769÷5 is
4.
∴ If
1769 paint bottles are equally packed into
5 boxes,
4 bottles will remain outside the boxes.
Next, calculate the case where the paint bottles are equally packed into
6 boxes.
Calculating
1769÷6,
So, the remainder of
1769÷6 is
4.
∴ If
1769 paint bottles are equally packed into
6 boxes,
5 bottle would remain outside the boxes.
Now, comparing the number of bottles remaining outside the boxes in each case,
Number of boxes the paint bottles are equally packed into |
Number of bottles left outside |
3 boxes |
2 bottles |
4 boxes |
1 bottles |
5 boxes |
4 bottles |
6 boxes |
5 bottles |
Comparing the number of bottles left outside, find that
1<2<4<5
∴ To leave the least number of paint bottles outside, the bottles must be arranged equally into
4 boxes.
