In 10th standard teacher arranged a surprised test for students. In round-I: Ajay got 8 marks for correct answers and 4 marks for incorrect answers and scored 20 marks. In round-II: Ajay got 5 marks for correct answers and 1 mark for incorrect answer and again he scored 20 marks. An another student Neeta observed these two situations and denote number of correct answer by x and incorrect answers by y. Based on the above information answer the following questions. (i) Represent situation given in round-I algebraically. (a) 2x+y=5 (b) 2x-y=5T (ii) Represent situation given in round-II algebraically. (a) 5x - y = 20 (b) 5x+y=20 (c) 8x+2y = 20 (c) x + 5y = 20 (iii) Number of questions, that answered correctly in each round is (a) 2 (b) 3 (c) 5 (iv) Number of questions that answered incorrectly in each round is (a) 5 (b) 10 (v) Total number of questions asked in both rounds, is (a) 5 (b) 10 fo (c) 15 (c) 15 all students so that the
