IMO A ... OA pls

W = n*m where n = number of fish , m =weight of fish

n = W/m is max when m is minimum as W is constant.

Thus 1 is sufficient.


statement 2 gives average weight , does not give any indication of minimum weight of fish..Thus insufficient.

From equilbrium strategy, minimum of one thing needs maximum of other thing to balance.

In statement 1, the minimum weight of tuna is mentioned. So it needs maximum count of tuna to balance.

Statement 2 provides the range.

Hence A.

Statement 1: We know that at minimum fish should weigh more than 5. But 5.1, 5.001, give different number of fish in the cart. Can we say that it is enough?

Yes, we can.

On a certain fishing boat that catches tuna, wheeled carts are used to move the fish around the deck. If a cart can hold 1,600 lbs of fish, what is the maximum number of tuna that can be put in one cart?

(1) A tuna will slip through the net and not get caught unless it weighs over 5 lbs --> 1600/5 = 320. Since the weight must be over 5 lbs, then the maximum number of tuna that can be put in one cart is 319. Sufficient.

(2) A net full of tuna, which is 100 fish, weighs on average 800 lbs. Clearly insufficient.

Answer: A.

Hope it's clear.
