Answer:

84

Step-by-step explanation:

Let x be marks of Tanvi.

It is given that Rahul get 12 more marks than Tanvi. So, the marks of Rahul is x+12.

The ratio of marks of Tanvi and Rahul is 3:4.

\dfrac{x}{x+12}=\dfrac{3}{4}

On cross multiplication we get

4x=3(x+12)

4x=3x+36

4x-3x=36

x=36

The value of x is 36.

It means Tanvi gets 36 marks and rahul gets 48 marks.

The sum of their marks is

36 + 48 = 84

Therefore, the sum of their marks is 84.
