The sum of three numbers A,B,C is 98 . if A:B =2/3 and B:C =5/8 , then B is ?
[A] 20
[C] 45
[B] 30
[D] 10

• Option B 30
  A:B=2:3,B:C=5:8
  A:B:C=10:15:24
  A+B+C=98
  B=15/49*98=30

• Given that,
  sum of A+B+C=98----(1)
  A/B=2/3 and B/C=5/8
  Now convert A/B and B/C in terms of B ==> A=2B/3 and C=8B/5
  Now substitute A and C in (1)
  2B/3+B+8B/5=98
  B=30
