Let the four numbers be a, b , c and d. (a + b + c)/3 = 16 (a + b + c) = 48 ----- (i) (b + c + d)/3 = 14 (b + c + d) = 42 ----- (ii) Given that last number is 17 i.e. , d = 17, now putting this value in (ii) (b + c +17) = 42 (b + c) = 42-17 (b + c) = 25 ----- (iii) Now, putting value of (iii) into (i), (a + b + c) = 48 a + 25 = 48 a = 48-25 = 23 therefore, the first number is 23.
