Question

The given question is followed by two statements; select the most appropriate option that solves the question.

Capacity of a solution tank A is 70% of the capacity of tank B. How many gallons of solution are in tank A and tank B?

Statements:

• A. Statement 1 alone is sufficient
• B. Statement II alone is sufficient
• C. Either statement 1 or 2 alone is sufficient.
• D. Both the statements 1 and 2 together are sufficient.

Answer 1

The correct option is D Both the statements 1 and 2 together are sufficient.

Both statements will be required as capacity is required and what portion of capacity is filled is also required.

From (ii) we get full capacity of tank A = 14000

So capacity of B is 20000
$=\left(\frac{14000}{7}\right)$

But for getting quality of solution we also need how much it is full.

Statement I gives A is 80% full and B is 40% full.
i.e. Vol. in A occupied = 80% of 14000
= 11,200

Vol. in B occupied = 40% of 20000
= 8000

Hence both statements will be required for finding out gallons of solution in A and B respectively.
