Answer 1

Answer:

800

Step-by-step explanation:

Given in an examination 3/40 of the total students used unfair means out of 3/4 caught red handed. if number of students who escaped being caught is 15 . Find the total number of students who appeared in the final examination? what values are promoted in above question​

Let the total number of students be s

Students who used unfair means are 3/40 x s

Students who were caught red handed are 3/40 s x 3/4 = 9 s /160 s

Students who escaped being caught are 3 s/40  - 9 s/160 = 15

                                                         12 s - 9 s / 160 = 15

                                                           3 s / 160 = 15

                                                          s / 160 = 5

                       s = 800

the total number of students who appeared in the final examination are 800
