Average 20 numbers is ‘x’. If the average of first 12 numbers is 72.5 while average of last 5 numbers is 82.2 and 13th, 14th and 15th numbers are (3x - 42), (x + 50) and 183 respectively. Find the 14th number.
According to question, => 20x = 72.5 × 12 + 82.2 × 5 + 3x – 42 + x + 50 + 183 => 16x = 1472 => x = 92 Therefore, 14th number = 92 + 50 = 142
