Question

Sachin scored 10 marks less than Ravi in an Examination. Suresh scored 5 marks more than Ravi. In total they scored 490 marks. What was the score of Sachin ?​

Answer 1

Answer:

155 marks

Step-by-step explanation:

Let Ravi's marks be x

Given that, Suresh's marks are 5 more than Ravi's :

Suresh's marks = x+5

Also, Sachin's marks are 10 less than Ravi's :

Sachin's marks = x-10

Given, total marks scored are 490.

i.e.; (x) + (x+5) + (x-10) = 490

therefore, x + x + 5 + x - 10 = 490

3x + 5 - 10 = 490

3x - 5 = 490

3x = 490 + 5

3x = 495

x = 495/3

x = 165

Therefore, Ravi's score is 165

From data, Sachin's score = x - 10

= 165 - 10 = 155

Sachin's score is 155 marks
