Please helpSolutionGiven that if we want to prepare strings

Solution

Given that if we want to prepare strings with 247 beads, we need 117 beads to complete some number of full strings. So, i assumed that there are x beads in each string. Then total beads is equal to 247*x-117.

If we want to prepare strings with 65 beads, we can prepare some number of full strings without any shortage. So i assumed that there are y beads in each string. Then total beads is equal to 65*y.

So, 274*x-117=65*y.

From this, y=(247*x-117)/65

And x and y are natural numbers.

So, take values of x such that y is also natural number by trail and error method.

I have mentioned the values of x and y earlier.

Substitute y value in 65*y to get total number of beads.
