Question: Julian has 80 Facebook friends. 60% are boys and 40% are girls. Boyd has twice as many friends who are girls and has 100 friends total. What percentage of Boyd’s friends are boys?
Answer with step-by-step thinking:
Julian's number of friends who are girls is .40 * 80 = 32. Boyd has twice as many friends as Julian who are girls, a total of 2 * 32 = 64. If Boyd has 100 friends, he has 100 - 64 = 36 boys. The percentage of boys in Boyd's Facebook friends is 36 / 100 * 100 = 36.
So the answer is 36.
