If the total marks in Mathematics, Physics, and Chemistry are 84,000 and their ratio is 3 : 4 : 5, what are the marks in Physics?
- 21,000
- 24,000
- 28,000
- None of these
Explanation
Ratio of Math : Physics : Chemistry = 3 : 4 : 5
Total parts = 3 + 4 + 5 = 12 parts
Total marks = 84,000
Value of 1 part = 84,000 / 12 = 7,000
Marks in Physics = 4 parts = 4 * 7,000 = 28,000
