Question

Q1.Q: The sum of three consecutive multiples of 3 is 72. What is the second largest number ?

Answer 1

Step-by-step explanation:

Let the three consecutive multiples of 3 be 3x, 3(x + 1) and 3 ( x + 2), i.e. 3x + 3 and 3x + 6

Given, 3x +3x + 3 + 3x +6 = 72

⇒ 9x + 9 = 72 ⇒ 9x=63 ⇒ x =7

∴ Largest multiple of 3 = 3 (x + 2) =3 (7 + 2)

3 x 9 = 27

Answer 2

Answer:

24

Step-by-step explanation:

let numbers = x, x+3,x+6

x+x+3+x+6 = 72

3x = 63

x= 21

The three numbers are = 21,24,27

24 is the second largest number
