Answer 1

Answer:

1) False

2) True

3) False

4) False

Answer 2

Answer:

The correct answer is option(C)

Step-by-step explanation:

Given,

The marks of Ritu in Physics, Chemistry, and Maths are 78,76,74

The marks of Renu in Physics, Chemistry, and Maths are 72,82,74

Recall the concepts:

The average score =$\frac{Sum\ of \ observations}{Total\ number \ of \ observations}$

Solution:

The marks of Ritu are 78,76,74

The total score of Ritu = 78+76+74 = 228

The total number of scores = 3

The average score Ritu = $\frac{228}{3}$ = 76

The marks of Renu = 72,82,74

The total score of Renu = 72+82+74 = 228

The total number of scores = 3

The average score of Renu = $\frac{228}{3}$ = 76

∴The average score of Ritu and Renu are equal

Hence the correct answer is option(C)
