R1 and R2 are two rectangular tanks. Which one of them has a greater capacity?

(1) Height of R1 is twice the height of R2.

(2) R1 has a square base of perimeter same as the perimeter of base of R2.

IMO E.

St 1. Height of R1 twice that of R2. St1 does not talk about base areas. Hence Insuff.

St 2. R1 has square base of perimeter same as R2 ( whose base may or may not be a square). St2 doesn't talk about heights. Hence Insuff.

1+2 together. We can have two bases with same perimeter having different areas.

for ex. T1 base = square of side 3. perimeter = 12 & area = 9. T2 base rectangle with sides 5,1. perimter = 12 & area = 5.

So insuff.

Hence E.

Kindly give me kudos if you liked the explanation...
