The number of jelly beans that Gabby had in the end is repeated. Make the number of jelly beans that Gabby had in the end the same. LCM of 1 and 3 is 3.
Number of jelly beans that Gabby had more than Penelope
= 21 u - 5 u
= 16 u
16 u = 176
1 u = 176 ÷ 16 = 11
Number of jelly beans that Penelope had at first
= 5 u
= 5 x 11
= 55
Answer(s): 55
