Answer / sp

first we will calculate the total area of the steel
required with nos of bar of 20 mm and area of one bar of 20
mm.
and then divide with area of one bar of 16 mm.
the result will be nos of bar of 16 mm dia.

In beam /column
Total cross section area of 20mm=total cross section area of
16mm

(3.14/4)*20*20=(3.14/4)*16*16*no

No=400/256
=1.56
