The following table shows the marks scored by A, B, C and D in four subjects i.e., Mathematics, Hindi, English and Science. Marks given are out of 100 . Study the table and answer the question.

Subject/Student	A	B	C	D
Mathematics	94	85	83	78
Hindi	86	78	74	82
English	75	73	70	74
Science	92	88	66	68

What is the ratio of 'the sum of the marks scored by A in Mathematics and Hindi' to 'the sum of the marks scored by C in Science and Hindi'?

Correct option is C

Given:

Marks scored by A:

Mathematics: 94   Hindi: 86

Marks scored by C:

Science: 66   Hindi: 74 

Solution:

Marks scored by A (Mathematics + Hindi): 94 + 86 = 180

Marks scored by C (Science + Hindi): 66 + 74 = 140 

Now, the ratio of these two sums is: 

​$$\text{Ratio of the sums} = \frac{\text{Sum for A}}{\text{Sum for C}} = \frac{180}{140} = \frac{9}{7}$$ 

​So, the ratio is $9:7$. ​
