If average score of A and B and B and C are equal to 40 and 48 respectively and average score of C and A is 44. Then find the average score of all three A, B and C.
A42
B43
C44
D45
Answer:
C. 44
Read Explanation:
Total score of A and B = 2 × 40 = 80
Total score of B and C = 2 × 48 = 96
Total score of C and A = 2 × 44 = 88
⇒ 2(A + B + C) = 80 + 96 + 88
⇒ A + B + C = 132
average of A, B and C = 132/3 = 44
