Answer :
Alex bought 8 oranges. Since he bought six apples and he bought twice as many pears as apples, he bought 12 pears. since he bought 4 more pears than oranges , you subtract 4 from 12, which gives you 8.
He bought twice as many pears as apples. We can say this as he bought 2 times more pears than Apples. Now that can be said as 2 times # of apples= # of pears. He also bought 4 more pears than oranges. So he bought #of oranges +4=#of pears. If he bought 6 apples he bought 2*6 pears and so he bought 12 pears. Now since he bought 4 more pears than oranges then all we do is the opposite which is 12-4=oranges.
He bought 6 apples, 8 oranges, and 12 pears.
He bought 6 apples, 8 oranges, and 12 pears.
