Question

Mr teo has some oranges and a few bags. He uses all the bags to pack the oranges. If he packs 5 oranges in each bag, he will be short of 4 oranges. If he packs 4 oranges in each bag, he will have 3 oranges left. What is the least number of oranges he has?

Answer 1

0.35

Explanation:

Answer 2

31 oranges

Explanation:

Let n be the number of oranges and m be the number of bags Mr. Teo has.

If he packs 5 oranges in each bag, then he packs 5m oranges in m bags and since he is short of 4 oranges,

`n=5m-4.`

If he packs 4 oranges in each bag, then he packs 4m oranges in m bags and since he has 3 oranges left,

`n=5m+3.`

Equate right sides of these two equations:

`5m-4=4m+3,\\ \\m=7.`

Hence,

`n=5\cdot 7-4=31.`
