Solution

The correct option is D
$3 : 7$

Total number of students in the class = $15 + 20$
= $35$
$\frac{N u m b e r o f b o y s}{T o t a l N u m b e r o f s t u d e n t s} = \frac{15}{35} = \frac{3}{7} (D i v i d i n g N u m e r a t o r a n d D e n o m i n a t o r b y 5) = 3 : 7$
So , the required ratio is $3 : 7$
So, Option (d) is the correct answer.
