Answer 1

Answer:

110

Step-by-step explanation:

Let maximum marks be x

Marks got by hari = 80 / 100 x – 8 = 4/5 x – 8

Marks got by Ravi = 70/100 x + 5 = 7/10 x + 5

4/5 x – 8 – 7/10 x – 8 – 5 = 2

4/5 x – 7/10 x = 2 + 13

x/10 = 15

x = 150

Therefore marks scored by Ravi  

= 7/10 x 150 + 5

= 105 + 5

= 110
