Let third number = $$100x$$ First number is 30% less than $$100x$$ and second number is 37% less than $$100x$$ => First number = $$70x$$ and Second number = $$63x$$ To make second number equal to first number, it should be enhanced by = $$70x - 63x = 7x$$ => Required % = $$frac{7x}{63x} imes 100 = frac{1}{9} imes 100 = 11.11\%$$ => Ans - (C)
