Detailed Solution
Download Solution PDFGiven:
Ratio of marks of A and B = 3 : 4
Ratio of marks of B and C = 4 : 5
Difference in the marks of C and A = 30
Formula Used:
To find the marks of B, use the combined ratio method.
Calculation:
Let the marks of A, B, and C be 3x, 4x, and 5x respectively.
Given that the difference in the marks of C and A is 30:
5x - 3x = 30
⇒ 2x = 30
⇒ x = 15
Marks of B = 4x = 4 × 15 = 60
Therefore, B gets 60 marks.
