Question

Karim scored 15 marks more than Rahim in an examination. Madan scored 10 marks less than Rahim. Totally they scored 110 marks. What was Karim's score?​

Answer 1

Step-by-step explanation:

Let the Rahim's marks be x

Karim marks = x + 15

Madan marks = x - 10

Total marks they scored = 110

x + (x + 15) + (x - 10) = 110

x + x + 15 + x - 10 = 110

3x + 5 = 110

3x = 110 - 5

3x = 105

x = 105/3

x = 35

Karim's score = x + 15

= 35 + 15

= 50 marks [Answer]

Answer 2

Answer:

Let Rahim's score be x .

So Karim's score is x+15,

Madan's score is x-10

Step-by-step explanation:

As per Qn,

x + x+15 + x-10 = 110

3x +5 = 110

3x = 105

x = 35

x +15 = 35 + 15

x+ 15 = 50

Hence Karim's score is 50 marks.
