The ratio of marks obtained by Shubham in theory to the total marks which can be obtained in theory ...........

Quant (SSC) Ratio, Proportion

The ratio of marks obtained by Shubham in theory to the total marks which can be obtained in theory is 7 : 10. Total marks which can be obtained in practicals were 20% of the total marks of theory. If Shubham got full marks in practical then find the ratio of total marks obtained by Shubham to the total marks which can be obtained in the subject (theory + practical)

Explanation:

Let, marks obtained by Shubham in theory and total marks of theory be ‘7x’ and ‘10x’ respectively
So, total marks (theory + practical) = 10x + 2x = 12x
Marks obtained by Shubham (theory + practical) = 7x + 2x = 9x
So, reqd. ratio = 9x / 12x = 3/4
