- 2:1 is the answer

- let the largest number be x and smallest number be y
now half of the small number is subtracted from larger numbr where the resulut will be three times than the smaller one as shown
x - y/2 = 3(y-y/2)
2x = 4y
x:y = 2:1
option : D - 11 years agoHelpfull: Yes(9) No(4)
- 2:1
Let the two. no. be x & y
x-y/2=y-y/2
x-y/2=3y/2
x=2y
x:y=2y:y
=2:1 - 11 years agoHelpfull: Yes(3) No(0)
- plzz tel 3(y-y/2)is clear from which line of ques?????
resultant thrice of smallest should mean that its =3y??? - 11 years agoHelpfull: Yes(3) No(0)
- 2:1
let x is smaller n y is largest.
y-x/2=3(x-x/2)
by solving we get y=2x
therefore the ratio is 2:1 - 11 years agoHelpfull: Yes(2) No(0)
- x-y/2=3(y-y/2)
x=2y
x/y=2/1
2:1 is ans - 11 years agoHelpfull: Yes(2) No(0)
- 2:1 is d ans
- 11 years agoHelpfull: Yes(1) No(1)
- ans- suppose x,y are the no. ,y is smaller ,
from Q. x-y/2=3*y/2;
x/y=2/1;
so x:y=2:1
