Initially the marbles they have in the ratio
J/D =13/9
Now they have 10 more marbles
A:
13x+10/9x+10 =7/4
52x+40=63x+70
this cannot be the no of marbles they can have (A)
E:
13x+10/9x+10 =23/8
104x+80=207x+230
this cannot be the no of marbles they can have (E)
B,C,D are the marbles they can have
Ans A,E
J/D =13/9
Now they have 10 more marbles
A:
13x+10/9x+10 =7/4
52x+40=63x+70
this cannot be the no of marbles they can have (A)
E:
13x+10/9x+10 =23/8
104x+80=207x+230
this cannot be the no of marbles they can have (E)
B,C,D are the marbles they can have
Ans A,E
