# A man has 2 times as many mangoes as his neighbour. Together they have 12 mangoes. How many mangoes does the neighbour have?

Let the number of mangoes the man has be M. As he has twice the number that his neighbor has, the number of mangoes with his neighbor is M/2

Together they have 12 mangoes. This gives M + M/2 = 12

=> (3/2)*M = 12

=> M = (2/3)*12

=> M = 8

The neighbor of mangoes with the neighbor is 8/2 = 4.

The neighbor has 4 mangoes.

If they have 12 total, your starting equation should be:

a+2a=12

3a=12  (consolidating the equation)

Narrowing down to the variable by dividing by 3 on each side):

3a/3=a

12/3=4

a=4

The neighbor has 4 and he has 8.

ok, lets say the neighbor has x mangoes. this means that the man has twice that or 2x. so together means:

x + 2x = 12                            combine like terms

3x = 12                                  divide both sides by 3

x = 4

since the neighbor had x mangoes, then this means the neighbor had 4 mangoes.
