M15 means 15mpa (N/mm^2) = 150( kg/cm^2).

M15 means 15Mpa (Mega pascal).
15Mpa = 150 bar.
(because 100000 pascal equal to 1 bar).
15Mpa = 150 bar.
(because 100000 pascal equal to 1 bar).

The question is for M15 not M150.
For,
M15 58d
M20 47d
M25 40d
M30 38d In tension

Please explain this question. How it is 58d?

D*130/4*0.6= 58d.
13oN/mm2=stress of mild steel,
And0.6=bond stress of M15 in wsm.

It's actually development length Ld that is asked here, calculate by formula Ld= (0.87*Fy* D)/4* Tbd.
On solving this you get 087*415*D/4*1.2*1.6= 47D. This is for M20 grade.
On solving this you get 087*415*D/4*1.2*1.6= 47D. This is for M20 grade.

Not for M150, grade 15, but this is nominal mix design not for mix design.
