Answer 1

Step-by-step explanation:

Given that:જો ગુ.સા.અ. ( 25,15) = 4x+1 હોય તો X =?

Meaning: If GCD(25,15)= 4x+1,then x=?

To find: Value of x

Solution:

To find the value of x,first find Greatest common factors of the two numbers.

Do prime factors of 25 and 15

$25 = 5 \times 5 \\ \\ 15 = 3 \times 5$

greatest common factor of 25 and 15 is 5.

But it is given that it is 4x+1

$GCD(25,15)=4x + 1 \\ \\ 5 = 4x + 1 \\ \\ 5 - 1 = 4x \\ \\ 4x = 4 \\ \\ x = \frac{4}{4} \\ \\ x = 1$

Thus, x= 1

From the given options,option C(x=1) is correct.

Hope it helps you.
