A) 400 \[c{{m}^{3}}\]
B) 500 \[c{{m}^{3}}\]
C) 450 \[c{{m}^{3}}\]
D) 100 \[c{{m}^{3}}\]
Correct Answer: A
Solution :
Suppose the total volume of water = x \[\therefore 100c{{m}^{3}}\times 0.5N=x\times 0.1N\] \[\therefore x=\frac{100\times 0.5}{0.1}=500c{{m}^{3}}\] Therefore the volume of water added \[=\text{Total}\,\,\text{volume--100c}{{\text{m}}^{\text{3}}}\] \[=500-100=400c{{m}^{3}}\].
