Answer:
25
Step-by-step explanation:
Let the number of white beads be w.
Then the number of blue beads is 5w since it is 5 times greater.
Total number of beads = number of white beads + number of blue beads = w + 5w
Total number of beads = 30
5w + w = 30
6w = 30
w = 5
number of blue beads = 5w = 5(5) = 25
