Riya got 40% more marks in Economics than in Business
Studies. If her average score in Economics, Business Studies, and Accounts is 95, and she scored 105 in Accounts, what was her score in Business Studies?Solution
ATQ,
Total marks in all three subjects = 95 × 3 = 285
Marks in Economics and Business Studies = 285 – 105 = 180
Let the marks in Business Studies be ‘x’.
Then marks in Economics = 1.4x
x + 1.4x = 180
2.4x = 180
x = 180 / 2.4
x = 75
So, marks in Business Studies = 75 marks
