Question

50 will be obtained by taking away 4 from thrice of a number.​

Answer 1

Answer:

5

Let the natural number be x.

Then according to the given condition,

3x 2 −4x=50+x

3x 2 −5x−50=0

3x 2 −15x+10x−50=0

3x(x−5)+10(x−5)=0

(3x+10)(x−5)=0

∴x= −10/3

and x=5.

Since, x is given to be a natural number, so x = 5.
