the sum of three no. is 68. if the ratio b/w 1st and 2nd is 2:3 and that b/w 2nd and 3rd is 5:3 then second no. is a)30 b)20 c)58 d)48 ?

Let the three numbers by x, y and z. 1 - x+y+z=68 2 - x/y = 2/3 which means x = (2*y)/3 3 - y/z = 5/3 which means z = (3*y)/5 Substituting x and z values from 2 and 3 in equation 1, we get y=30
