Since Michaela needs 20 oranges to eat to her full, and Cassandra eats twice as much to have her full, Cassandra needs 2 * 20 = 40 oranges to eat. They eat 20 + 40 = 60 oranges together to have their fill. If they picked 90 oranges today, after eating 60 together, 90 - 60 = 30 oranges would remain.
 The answer: 30 <hau> Mene ne tambaya don wannan ma'anar ma'ana, da kuma amsar da ta dace? Tunda Michaela tana buƙatar lemu 20 don cinyewa, kuma Cassandra tana cinye sau biyu don cikawa, Cassandra yana buƙatar 2 * 20 = 40 lemu don cinyewa. Sun ci 20 + 40 = 60 lemu tare don su cika. Idan suka tsince lemu 90 a yau, bayan sun ci 60 tare, 90 - 60 = lemu 30 za su rage.  Amsar: 30
