A number of pencils were shared out among Bisi, Sola and Tunde in the ratio of 2:3:5 respectively. If Bisi got 5, how many were shared out?
A
15
B
25
C
30
D
50
correct option: b
Let x represent total number of pencils shared
B : S : T
2 : 3 : 5
2+3+5 = 10
(\frac{2}{10}) x x = 5
(\frac{2x}{10}) = 5
2x = 50
x = 25
