In a particular examination, students securing more than 50% are considered to have passed the exam. The ratio of the students who passed the exam to the total numbers of student was obtained as 7:8. If 49 students passed the exam, then the total number of students who appeared for the examination is (A) 56 (B) 62 (C) 68 (D) 76 Share with your friends Share 0 Sanjari Kalantri answered this Dear Student, Let the total number of students be x.We have the ratio of the number of students who passed to the total number of students as 7:8 = 78; and 49 students passed the examination.Therefore, 78 of x = 49⇒7x8 = 49 ⇒x = 49 × 87 = 56.Thus, there are a total of 56 students who appeared for the examination.NOTE: The first statement about 50% marks required to pass the examination is just a statistic to confuse - it isn't required to solve this question. 0 View Full Answer Rose Kakrania answered this the answer is (a) as, let the total students be x ratio of students passed to total students is 7:8 students passed is 49 so we can say, 7:8 :: 49:x 7x=8*49 7x=392 x=392/7 x=56 hope you got it :) 0 Manan answered this it is because if we simplify 49:56 =7:8 -1 Jigyasa answered this HI TAKE TOTAL NUMBER OF STUDENTS AS x 7:8 AS 7/8 7/8 STUDENTS HAVE PASSED SO, 7/8 X x = 49 x = 49 X 8/7 x = 56 0 Jigyasa answered this X IS MULTIPLY SIGN 0
