Question
The marks obtained by A is 60% more than B, and the marks obtained by C is 180 more than the difference of A and
B. If C obtained 330 marks, then find the marks obtained by
A.
Solution
ATQ, Let the marks obtained by B be x. So, marks obtained by A = 1.60x According to question, (1.60x – x) + 180 = 330 0.60x = 330 – 180 0.60x = 150 x = 150 / 0.60 x = 250 Therefore, marks obtained by A = 1.60 × 250 = 400
