Question

Multiplication of three numbers is 12144 and the sum of three numbers is?

Answer 1

Let the three number be x , x+1 , x+2

Acc to Ques, x.(x+1).(x+2) = 12144

x.(x² + 3.x + 2) = 12144

x³ + 3.x² + 2.x - 12144 = 0

Therefore, 22 is a root of this Equation

By solving, we get (x - 22) .( x² + 25.x + 552)

Rest two roots are imaginary

So, x = 22

The sum of number= 22 + 23+ 24

Sum of Numbers = 69
