Answer 1

Answer:

Let the 3rd no. be x

Step-by-step explanation:

atq

(x + 3×x + 2×3×x) / 3 = 10

10x / 3= 10

10x = 30

x = 3

Answer 2

let the third number be x.

second number=3x

first number=3x×2=6x

average=10

(first + second + third)/3=10

(6x+3x+x)/3=10

(10x)/3=10

x=10×3/10

x=3

first number=6x=6×3=18

second number=3x=3×3=9

third number=x=3

the largest number is 18
