Question
The average of four consecutive odd numbers is 47. What
is the largest of these numbers?Solution
Let the four consecutive odd numbers be x, x + 2, x + 4, x + 6. Their average is (x + x + 2 + x + 4 + x + 6)/4 = 47. Simplify: (4x + 12)/4 = 47. 4x + 12 = 188. 4x = 176. x = 44. The largest number = x + 6 = 44 + 6 = 50. Correct Option: c
