Juan ate 1/3 of the jelly beans in a bag. maria ate 3/4 of the remaining jelly beans in the bag, after which there were 10 remaining

Juan ate 1/3

Jelly beans remaining = 1 - 1/3 = 2/3

Maria ate 3/4 of the remaining = 3/4 x 2/3 = 1/2

Jelly beans remaining = 2/3 - 1/2 = 1/6

1/6 of the jelly beans = 10

Total number of jelly beans = 10 x 6 = 60

Answer : There are 60 jelly beans in the bag at first.
