Complex A has a composition of H_(12) O_6 Cl_3 Cr . If the complex on treatment with conc. H_2 SO_4 loses 13.5 % of its original mass, the correct molecular formula of A is : [Given : atomic mass of Cr=52 amu and Cl= 35 amu]

The formula in which a certain integral involving some parameters in connected with some integrals of lower order is called a reduction formula. In most of the cases the reduction formula is obtained by the process of integrating by parts. Of course, in some cases the methods of differentiation are adopted.Now answer the question:If I_(m,p)=intx^m(a+bx^n)^pdx and I_(m,p)=(x^(m+1)(a+bx^n)^p)/(m+1)-f(m,n,p,b)I_(m+n,p-1) , then the value of f(1,2,3,4) is equal to (A) 8 (B) 10 (C) 12 (D) none of these
