We know, for RCC, max. Aggregate size = 1/5th of the least lateral dimension of mould.
Similarly for PCC, max size of aggregate is 1/4th of least dimension of mould.
Here ,if it is RCC, Max size of aggregate =(1/5)*100 mm = 20mm.
If PCC, Max aggregate size = (1/4)*100 = 25 mm.
Similarly for PCC, max size of aggregate is 1/4th of least dimension of mould.

If PCC, Max aggregate size = (1/4)*100 = 25 mm.

For massive structure =40mm.
For RCC =20mm.
For floors =10mm.
For RCC =20mm.
For floors =10mm.

How this is possible?
You can use max of 20mm not 20 cm.
You can use max of 20mm not 20 cm.

I think the right answer is 20mm.

For;
Massive structure = 40mm.
RCC = 20mm.
PCC = 10mm.
Massive structure = 40mm.
RCC = 20mm.
PCC = 10mm.

If it's RC structure that maximum size of the coarse aggregate is 1/5th min dimensions of RC member so =1/5*10=2cm (20mm).
Otherwise, if it's pc structure the maximum size of the coarse aggregate is 1/4th of the min dimensions of PC member so=1/4*10=2.5cm(25mm).
Now for this question they mentioned cube that means it's pc structure so the answer will be the 25mm is correct.

38mm aggregate for 150mm cube and 19mm for 100mmcube.

According to me, it will be 20 mm not at 20cmm.
