Detailed Solution
Download Solution PDFGiven:
Total marks in English and History = 140
English marks = 2.5 × History marks
Formula used:
Let History marks = x ⇒ English marks = 2.5x
Total = x + 2.5x = 140
Calculation:
x + 2.5x = 140
⇒ 3.5x = 140
⇒ x = \(\frac{140}{3.5} = 40\)
English marks = 2.5 × 40 = 100
∴ The correct answer is 100 marks
