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
250 marks in Hindi
312 marks in Computer Science.
Hope, it helps !
