SSC CGL 201918)A is 25% more than B and B is 40% less than C. If C is 30% more than D, then by what percent is A less than D?
2.5
Let B be 100, then A will be 125 ;
Now; \( {60 \over 100}C = 100 \) then; \(C = {500\over 3}\) ;
Also, \({130\over 100}D = C = {500\over 3}\) ; then \(D= {5000 \over 3 \times 13}\) ;
\({A \over D } \times 100 = {125 \times 3 \times 13\over 5000}\times 100= {195\over 2}\)%
Since we have to calculate less than percentage it will be \(100-{195\over 2} = 2.5\) %
