Question:
A student got 33⅓% marks in an exam and failed by 20 marks. If he had got 50%, he would have passed by 10 marks. Find total marks.
एक छात्र को परीक्षा में 33⅓% अंक मिले और वह 20 अंकों से फेल हो गया। यदि उसे 50% मिलते, तो वह 10 अंकों से पास हो जाता। कुल अंक ज्ञात कीजिए।
Options:
- a) 180
- b) 150
- c) 200
- d) 240
- a) 180
- b) 150
- c) 200
- d) 240
correct answer : a)
Explanation:
Let total marks be x. Pass mark = (33.33/100)x + 20 = (50/100)x – 10. (50 – 33.33)% of x = 30 => 16.67% of x = 30 => (1/6)x = 30 => x = 180.
माना कुल अंक x हैं। पास अंक = (33.33/100)x + 20 = (50/100)x – 10. x का (50 – 33.33)% = 30 => x का 16.67% = 30 => (1/6)x = 30 => x = 180।
