110. If s(s+s1+s2)=9,s1(s+s1+s2)=16 and s2(s+s1+s2)= 144, then the what is the value of “s”?

a.7/11 b.1/11 c.11/13 d.9/13

Ans: Let s+s1+s2 =x;

Then s(x)=9 –(1)

S1(x)=16 — (2)

S2(x)=144 –(3)

Add above three equations s(x)+S1(x)+S2(x)=9+16+144

x(s+s1+s2 ) = 169

x2=169

x=13

substitute x value in equation(1) so s=9/13
