Answer 1

Answer:

Sameer scores 208 marks in English

250 marks in Hindi

312 marks in Computer Science.

Step-by-step explanation:

Hi,

Let 'X' be the number of marks Sameer had scored in English

Given that he scores 42 marks more in Hindi than English,

hence marks scored in Hindi =X+42

Given that Sameer scored 1 and 1/2 times as many marks in english in

Computer Science,

Marks Scored in Computer Science =3/2^ * X= 3X / 2 .

Given that Sameer scores 77% marks in all 3 subjects

So, X + (X + 42) + (3X / 2) = 770

7X / 2 + 42 = 770

X / 2 + 6 = 110

X / 2 = 104

X = 208 .

Hence Sameer scores 208 marks in English

Given that Sameer scored 1 and 1/2 times as many marks in english in

Computer Science,

Marks Scored in Computer ince=3/2^ * X= 3X / 2 .

Given that Sameer scores 77% marks in all 3 subjects

So, X + (X + 42) + (3X / 2) = 770

7X / 2 + 42 = 770

X / 2 + 6 = 110

X / 2 = 104

X = 208 .

Hence Sameer scores 208 marks in English

250 marks in Hindi

312 marks in Computer Science.

Hope, it helps!
