(C) Let the third number be $100$.Since the first number is $10\%$ less than the third number,the first number $= 100 - 10 = 90$.Since the second number is $25\%$ less than the third number,the second number $= 100 - 25 = 75$.To make the second number equal to the first number,the increase required is $90 - 75 = 15$.The percentage increase required $= (\frac{15}{75}) 	imes 100$.$= (\frac{1}{5}) 	imes 100 = 20\%$.

Two numbers are $10\%$ and $25\%$ lesser than a third number. By what percentage must the second number be increased to make it equal to the first number (in $\%$)?
