Question

the average of three numbers is 48. Second number is greater by 8 than first number and less than third number by 14 Find the third number ​

Answer 1

let the first no. be x

second no. is x+8

third no. is x-6

=x+(x+8)+(x-6)/3=48

=3x+2=48×3

=3x=144

=x=48

Answer 2

Answer:

Step-by-step explanation:

let the first number be x,

$Second \: Number = x + 8 \\ \\ Third \: Number = x + 8 + 14 = x + 22 \\ \\ A.t.q. \\ \\ \frac {x + 8 + x + 22 + x}{3} = 48 \\ \\ \frac {3x + 30}{3} = 48 \\ \\ </p><p> \frac {3(x + 10)}{3} = 48 \\ \\ x + 10 = 48 \\ \\ x = 48 - 10 = 38 \\ \\ first \: Number = 38 \\ \\ Second \: number = x + 8 = 8 + 38 = 46 \\ \\ Third \: number = x + 22 = 38 + 22 = 60$
