Since here, it asked for the permissible stress of concrete in bending compression and in WSM we know that for finding the permissible stress we divide it by 3 (i.e. FOS for concrete) in WSM so after dividing.
300 kg/cm2 ÷ 3 = 100 kg/cm2 should be the answer.
300 kg/cm2 ÷ 3 = 100 kg/cm2 should be the answer.

I want to know concrete grade number for 240 kg/cm2.

Wrong answer, according to question,
The permissible compressive strength is required not characteristics compressive strength.
So, direct permissible compressive strength is 75N/mm^2.
And for bending com str is 96N/mm^2.

M 25 grade of concrete the comprehensive strength is 350 to 400 kg/cm^2 is ok or not?

m15-compressive strength 15n/mm2 in maximum.
1N = 100g.
m20-20N/mm2.
m30-30N/mm2.
1N = 100g.
m20-20N/mm2.
m30-30N/mm2.

Permissible compressive stress in concrete = 0.33 fck = 100 kg/cm^2.
