Diana and Farhan have a total of 8 sweets. It is mentioned that Diana has 2 less than Farhan. Therefore, if we assume that Farhan has x sweets, Diana will have x - 2 sweets. The sum of their sweets is 8, so we can set up the equation x + (x - 2) = 8. Simplifying this equation, we get 2x - 2 = 8. Solving for x, we find that Farhan has 5 sweets.

Koko the koala slept for 20 hours yesterday, so he did not eat any leaves during that time. However, when he is awake, he eats 50 grams of leaves per hour. Therefore, the total amount of leaves he ate yesterday can be calculated by multiplying 50 grams per hour by the number of hours he was awake. Since he slept for 20 hours, he was awake for 24 - 20 = 4 hours. Therefore, he ate 50 grams/hour * 4 hours = 200 grams of leaves yesterday.
