A candidate who gets 30% of the marks fails by 50 marks. But another candidate who gets 45% marks gets 25 marks more than necessary for passing. Find the number of marks for passing? |

Answer» Let total Marks is: $X$ ACCORDING to the question $0.3x + 50 =$ PASSING Marks & $0.45x - 25 =$ Passing Marks On Solving $0.3x + 50 = 0.45x - 25$ $0.15x = 75$ $x = 500$ Passing Marks $= 0.3 \times 500 + 50 = 200$ |
