Rupali scored twice as many marks in maths as she did in science. Her total marks in maths, science and computer are 234. If the ratio of her marks in maths and computer is 4 : 3. Find Rupali’s marks in maths.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 104.
Let Science = x
Then Maths = 2x
Maths : Computer = 4 : 3 → Computer = (3/4) × Maths = (3/4) × 2x = 1.5x
Total = x + 2x + 1.5x = 4.5x = 234
x = 234 ÷ 4.5 = 52
Maths = 2x = 104
