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

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.

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