Set A contains seven numbers and the average of these numbers is 41. Set B contains five numbers and the average of these numbers is 44. The overall average of both the sets is:

42.25

Sum of set of 7 numbers of A = 7 × 41 = 287

Sum of set of 5 numbers of B = 5 × 44 = 220

Total sum of both sets = 287 + 220 = 507

Average of both the sets = \(\frac{507}{12}\) = 42.25
