Answer 2

Answer:

85

Step-by-step explanation:

Average Score = Marks in all subjects gained / total marks in all subjects

therefore....Let the marks scored in 6th subject be X

then total marks gained = 80 + 75 + 62 + 50 + 91 + X = 259 + X

and total number of subjects = 6

Average = 74

therefore.... 74 = (259 + X)/ 6

74*6 = 259 + X

444 = 259 + X

X = 85

Hence marks scored in 6th subject = 85

hope it helps :)
