Question

The ratio of the factorial of a number x to the square of the factorial of anothe no.,which whwn increased by 50% gives remainder no.,is 1.25.Find no. X

Answer 1

lest suppose
another number= y
so,
 increase= y+50% of y = x
and y = x/ 1.5
also,
 x!/(y!)² =1.25
x! /[(x/1.5)!]² =1.25

Answer 2

Let us suppose and thus take another number= y.

so, increase= y+50% of y = xand y = x/ 1.5.

Among this factor takes also,  x!/(y!)² =1.25 x! /[(x/1.5)!]² =1.25.

The factors are considering n factors and include another number by increasing 50% of required number.

It includes co prime numbers in order to evaluate the remainder actually works.
