Answer 1

Answer:

The marks scored by Ranu is 50 marks and the marks scored by Shanu is 35 marks.

Step-by-step explanation:

Let the marks of Ranu and Shanu be in the ratio 10x:7x

Therefore, 10x+20+7x+20 = 5x+4x

Or, 10x+7x+20+20 = 5x+4x

Or, 17x+40 = 9x

Or, 17x-9x = 40

Or, 8x = 40

Or, x = 40/8 = 5

Marks of Ranu = 10x = 10×5 = 50

". " Shanu = 7x = 7×5 = 35.
