Priya got 9 marks more in History than what she got in Geography. Her history marks are 56% of the sum of her History and Geography marks. What are her Geography marks? Correct Answer 33
Let Priya’s marks in Geography and History be ‘x’ and ‘y’ respectively
She got 9 more marks in History than in Geography,
⇒ y = x + 9
Also, her History marks is 56% of sum of both marks
⇒ y = 56% of (x + y)
⇒ y = 0.56x + 0.56y
⇒ 0.44y = 0.56x
Substituting for y,
⇒ 0.44(x + 9) = 0.56x
⇒ 0.44x + 3.96 = 0.56x
⇒ 0.12x = 3.96
⇒ x = 3.96/0.12 = 33
∴ Priya’s Geography marks = 33
