Question : -

4/3 of a number is more than 3/4 of its number by 1 . find the number .

Given : -

  • 4/3 of a no. is more than 3/4 of its no. by 1

To Find : -

  • We have to find the number .

To Assume : -

  • Let the no. be x

So Solution goes from here :

According to question 4/3 of a number is equal to :


\longmapsto \: (4)/(3) * x

Which means ,


\longmapsto \: (4x)/(3)

According to question 3/4 of a number is equal to :


\longmapsto \: (3)/(4) * x

Which means ,


\longmapsto \: (3x)/(4)

Now , forming equation :

As the question says that 4/3 of a number is more than 3/4 of its number by 1 . So :


\longmapsto \: (4x)/(3) = (3x)/(4) + 1

Now , transposing 3x/4 to left hand side :


\longmapsto (4x)/(3) - (3x)/(4) = 1

Now , taking L.C.M :


\longmapsto \: (4(4x) - 3(3x))/(12) = 1

Now by calculating :


\longmapsto \: (16x - 9x)/(12) = 1

Now Subtracting 16x with 9x and transposing 12 to right hand side :


\longmapsto \: 7x = 12

So ,


\longmapsto \: \boxed{ \bold{ x = (12)/(7) }}

  • Therefore , the number is 12/7 .
