Marks: +1, -0

Two numbers are

30 \%

and

60 \%

respectively more than a third number. The two numbers arein the ratio of:

22: 23
13: 16
16: 16
14: 13

Solution:

Let the three numbers be

x, y

and

z

.
From the question

x=z+30 \%

of

z

={130}/{100} \ {z}

And

y=z+60 \%

of

z={160}/{100} z

Thus

{x}/{y}={{130}/{100} z}/{{160}/{100} z}={13}/{16}

⇒ x: y=13: 16
