We know that, Average = Sum of all quantities/number of quantities Average of 7 numbers = 28 ∴ Sum of all numbers = 28 × 7 = 196 Average of first 3 numbers is 23. Sum of first 3 numbers = 3 × 23 = 69 Average of last 3 numbers os 42. Sum of last 3 numbers = 3 × 42 = 126 4th number = 196 – 69 – 126 = 1
