Question
The marks obtained by A is 25% more than B, and the
marks obtained by C is 160 more than the difference of the marks obtained by A and B. If C obtained 175 marks, then find the marks obtained by A.Solution
Let the marks obtained by B be ‘x’. So, marks obtained by A = 1.25x According to question, (1.25x – x) + 160 = 175 0.25x = 175 - 160 0.25x = 15 x = 15/0.25 x = 60 Therefore, marks obtained by A = 1.25 × 60 = 75 marks
