  @raman_sharma LET the remaining areas in cyclic order from left be e,a, d, b.and the shaded area be c. a+b+c =1/2(a+b+c+d+e+97)a+b+c = d+e+97ord+e+97 = a+b+c -------(1) similarly, e+c+d = 1/2(a+b+c+d+e+97)=>e+c+d= a+b+97 ------(2) subtract (2) from (1) c-97 = 97-c=>c=97

  We can do it another way too: Put x= y,F(2x) = f(x)^2Put y=2xF(3x)= f(x)^3=>f(nx)=f(x)^n F(-8)=F(-2×4)=f(4)^-2=1/9
