Directions(Q.1 to Q.10 ):

Value A is three times of value B. If value of C is 62.5% of difference between value of A and B, then value C is what percent of B?

Lets A is 3x and B is x

C = $left( {3x - x} ight) imes frac{{62.5}}{{100}} = 2x imes frac{5}{8} = 1.25x$

Required percent = $frac{{1.25x}}{x} imes 100 = 125{ m{\% }}$
