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 ' Question Image '
Then we will first calculate Question Image of the number.
Therefore, we have Question ImageNow, calculating Question Image of ' Question Image '
So, we will have Question ImageSince, it's given that Question Image of a number exceeds its Question Image or we can say that Question Image is greater than Question Image by 44 .
Hence, from above we have,
Question Image Take LCM for solving the above equation
