Louis has 5 oranges and 3 apples. Samantha has 8 oranges and 7 apples. If Marley has twice as many oranges as Louis and three times as many apples as Samantha, how many fruits in total does Marley have?
Marley has twice as many oranges as Louis (who has 5 oranges) for a total of 2*5 = <<2*5=10>>10 oranges
He also has thrice as many apples as Samantha (who has 7 apples) for a total of 3*7 = <<3*7=21>>21 apples
Marley has a total of 10+21 = <<10+21=31>>31 fruits
