The marks obtained by A is 25% more than B, and the marks obtained by C is 144 more than the difference of the marks obtained by A and B. If C obtained 190 marks, then find the marks obtained by A.
Let the marks obtained by B be ‘x’. So, marks obtained by A = 1.25x According to question, (1.25x – x) + 144 = 190 0.25x = 190 - 144 0.25x = 46 x = 46/0.25 x = 184 Therefore, marks obtained by A = 1.25 × 184 = 230 marks
