Question

Karim score 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

Answer:

50

Step-by-step explanation:

Let Rahim's score be a.

hence, Karim's score = a+15

thus, Madan's score = a-10

Total score = 110

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

3a+15-10 = 110

3a + 5 = 110

3a = 110 - 5

3a = 105

a = 105/3

a = 35

thus, Rahim's score = a = 35

Karim's score = a + 15 = 35 + 15 = 50

Answer 2

Answer:

KARIM'S TOTAL SCORE IS 50

Step-by-step explanation:

LET RAHIM'S SCORE BE x

THEN KARIM'S SCORE = x + 15

AND MADAN 'S SCORE = x - 10

So, According to the question ,

x + x - 10 + x + 15 = 110

3x + 5 = 110

3x = 110 - 5

3x = 105

x = 105 /3

= 35

Since x i.e Rahim's score is 35

Karim 's score = 35 + 15

= 50

So, KARIM'S score is 50 .
