Sum of three nos is 98. The ratio between 1 and 2 is 2:3. The ratio between 2 and 3 is 5:8 .
Find the second no?

• ans is 30
  that is
  x+y+z=98
  x/y=2/3
  x=2y/3
  and
  y/z=5/8
  z=8y/5 subtitute this is x and z
  2y/3+y+8y/5=98
  y=30

• Numbers are in ratio of 10:15:24.
  
  Sum =98.
  
  so numbers are 20,30,48.
  
  Second number is 30.

• 
  Solving these 3 simultaneous equations
  X + Y + Z = 98, 3X – 2Y = 0 and 8Y – 5Z = 0,
  We get Y(the second number) = 30

• (2:3)*5=(10:15)
  (5:8)*3=(15:24)
  therefore the three numbers are in the ratio 10:15:24
  the second number is (15/(10+15+24))*98=30

• let x y z be the 3 no.x=2/3y,z=8/5y
  ans.is 30

• let us suppose three no. are a, b,c.
  a:b=2:3,and
  b:c=5:8;
  a:b:c=10:15:24;
  so b=b/(a+b+c)*90=15/49*98=30 ans.

• Let x,y,z be numbers.
  x/y=2/3 , So, 3x=2y. And y/z=5/8 , So 8y=5z
  Sum is 98, So 2y/3+y+8y/5=98. Therefore y=30
  Numbers are 20,30,48

• Let Us assume three numbers as A , B , C.
  Given Ratio :-
  A : B = 2 : 3
  B : C = 5 : 8
  Find A:B:C = 10 : 15 : 24 ; 10x + 15x + 24 = 98 => 49x = 98 ; X = 2
  Second Number = 15x = >15(2)=30
  Ans = 30

• x+y+z=98
  x:y=2:3 x 5
  y:3=5:8 x 3
  x:y:z=10:15:24 x 2
  x:y:z=20:30:48
  20+30+48=98,So the second number is 30

• ans: 30
  
  x+y+z=98
  x:y=2:3
  y:z=5:8
  then x=20 y=30 z=48

• ans is 30
  that is
  x+y+z=98
  x/y=2/3
  x=2y/3
  and
  y/z=5/8
  z=8y/5 subtitute this is x and z
  2y/3+y+8y/5=98
  y=30
