Detailed Solution

Concept- As it is known that the three fifths of a number are bigger by 44, we first let the number be "x" before determining its three fifths and two sevenths. Finding the difference between two numbers that are calculated in terms of 'x' and equal 44 is followed by solving the equation that results to determine the value of 'x' and, consequently, the necessary answer to the provided issue.
For this let the number is '

'
Then we will first calculate

of the number.
Therefore, we have

Now, calculating

of '

'
So, we will have

Since, it's given that

of a number exceeds its

or we can say that

is greater than

by 44 .
Hence, from above we have,

Take LCM for solving the above equation

On cross multiplying we have,
