please give ratio for M25to M40. because the ratio 
available in IS code only M10-M20, most case M25,so more 
then M25 ratio is our own preparation. so my suggestion is 
M20 or M25.

Answer

M40
because its have more cement content and it also depends 
upon what is mix design if you are giving cement content in 
M20 more than M40,then M20 will give higher strength than 
M40

  Re: which grade of concrete is the strongest? M20,M25,M30,M35 or M40?
Answer
# 8
M40 becoz the ratio of cement:sand:aggregate  is higher 
then the other. which are the core factor for any mix. the 
property of any mix like compreesive strength, 
characterstic strength etc . largely depends on the ratio.
