Question

The difference between two whole numbers is $66$ and one number is four times the other number. If $10$ is added to both the numbers, then the ratio can be

• A. $15:32$
• B. $7:19$
• C. $14:39$
• D. $16:49$

Answer 1

The correct option is D $16:49$

Let numbers are $x$ & $y$

$x-y=66---\left(I\right)$

$x=4y----\left(II\right)$

$3y=66$

$y=22,x=88$

New no $X=98Y=32$

ratio $=\frac{98}{32}=\frac{49}{16}$

or $16:49$
