Answer 1

Answer:- The value of p = 388.

and the value of q = -336.

NOTE:- The values are looking so weird but it's right value. We can prove it by putting the value of p and q in given frequencies and then add it the value will definitely come 120.

PROVING

17+388+32+(-336)+19=120

49+388-336+19=120

68+52=120

120=120

HENCE PROVED.

YOU DON'T NEED TO PROVE THIS. I JUST GAVE TO YOU FOR MORE CLARITY SO THAT YOU DON'T GET CONFUSED.

YOUR SOLUTION IS ONLY IN TWO ABOVE PICS.

THANKS.
