A fruit merchant has a lot of fruits, of which 3/5 are apples and the rest are oranges. He sold 65438+2/3 apples and oranges. He also has 40 apples and oranges.

Ask him how many apples he has been selling.

Ask him how much fruit he used to have.

There is always fruit:

40/{3/5 *( 1-2/3) +( 1-3/5)*( 1- 1/4)}=80

Apple has: 80 * 3/5 = 48

Apples sold: 48*2/3=32

therefore

(a)32

80 people
