Susan got 72 marks in English out of 120 and 70 marks in Hindi out of 150 the maximum marks in the mathematics paper 180 if she got 60 %marks in all the three papers combined, how many marks did she get in mathematics?
Answers
Answer:
Total marks in English = 120
Total marks in Hindi = 150
Total marks in Mathematics = 180
So, overall mark = 120+150+180 = 450
Total mark obtained by Susan = 60% of 450
= 450 x 60/100 = 45x6 = 270
Therefore, marks obtained in Maths = 270-72+70 = 270-142=128
The answer is 128. Hope this helped

Step-by-step explanation:
Answer:
The marks scored by Susan in Mathematics = 128 marks
Step-by-step explanation:
Marks obtained by Susan in English in a total of 120 = 72 marks
Marks obtained by Susan in Hindi in a total of 150 = 70 marks
The maximum marks of Mathematics = 180
The total marks of these three subjects = 120 + 150 + 180 = 450 marks
Given that Susan scored 60% marks in all the three papers combined
Let x be the marks scored by the Susan in Mathematics in a total of 180.
Therefore, we can form the equation as,
( (72 + 70 + x)/450 ) × 100 = 60
72 + 70 + x = (60/100) × 450
72 + 70 + x = 270
142 + x = 270
x = 270 - 142 = 128 marks
The marks scored by Susan in Mathematics = 128 marks
