Question

Ratio of three numbers is 3:4:7 and the multiplication of this is 18144 then the numbers are respectively.​

Answer 1

Let:-

The numbers be 3x, 4x and 7x respectively

Then:-

According to question

➨ 3x * 4x * 7x = 18144

➨ 84x³ = 18144

➨ x³ = 18144/84

➨ x³ = 216

➨ x³ = 6³

➨ x = 6

Therefore:-

We can find all values by using value of x as-

3x = 3*6 = 18

4x = 4*6 = 24

7x = 7*6 = 42

Hence:-

The numbers are 18, 24 and 42 respectively.

Answer 2

Answer :

Let, numbers be 3x, 4, and 5x

A.T.Q,

➝ 3x * 4x * 7x = 18144

➝ 12x² * 7x = 18144

➝ 84x³ = 18144

➝ x³ = 18144/84

➝ x³ = 216

➝ x = ³√(216)

➝ x = 6

So, numbers are :

• 3x = 18
• 4x = 24
• 7x = 42
