The average of 4 positive integers is 59. The highest integer is 83 and the lowest integer is 29. The difference between the remaining two integers is 28. Which of the following integers is the highest of the remaining two integers?
Note
Sum of four integers = (59 × 4) = 236.
Let the required integers be x and (x - 28).
Then, x + (x – 28) = 236 – (83 + 29) = 124.
⇒ 2x = 152
⇒ x = 76.
Hence, the required integer = 76
