Answer 2

Question:-

What number has to be added to each term of 3:5 to make the ratio 5:6

Solution:-

3:5 =

$\frac{3}{5}$

5:6 =

$\frac{5}{6}$

Let the number to be added be x

So, According to question

$\frac{3 + x}{5 + x} = \frac{5}{6}$

Cross multiply

$6(3 + x) = 5(5 +x)$

$18 + 6x = 25 + 5x$

$6x - 5x = 25 - 18$

$x = 7$

Final Answer:-

The number to be added is 7

Option b is correct
