Time ............... Rate .............. Work

2.5 ..................... \(\frac{1}{2.5}\) ................. 1 (Small ship)

x .......................... \(\frac{2}{2.5}\) ..................... \(\frac{2x}{2.5} = \frac{4x}{5}\) (Big Ship; twice the rate of small ship)

Load in big ship is \(\frac{4x}{5}\) times that of small ship

Answer = D

Bunuel: Kindly update OA for this question. Thanks

Say the large ship is twice as large as the small one (so say 2 loads of a small cargo ship fit into a large cargo ship). In this case at double the rate the 2 times larger ship will be loaded in the same 2.5 hours, so we'd have that x=2.5 hours. Now substitute x=2.5 into the answer choices to see which option gives 2. Only D fits.

Answer: D.

D.

lets Say V1 is vol of small cargo and v2 is large cargo
r1 = v1/2.5
r2 = 2r1

x = v2/r2
x= v2/2v1/2.5

x= 5v2/4v1
v2/v1 = 4x/5 SO D

Sol:

work done by small ship = A (rate ) * 5/2 (time)= 5A/2

Work done by large ship = B(rate)* T = 2A*X

ratio = Large/small ship = 2AX/(5A/2) = 4X/5

Rate Time Work

1/2.5 2.5 1
2/2.5 X (2/2.5)X

1* What = 2/2.5 X

What = (2/2.5)X

Hence (D)

Work = rate *time;

r1 t1 = 2.5 * ra;
r2t2 = X*2 rb;

2.5 * ra = X * rb;

ratio = 4X/5;

Let Small ship capacity be 'S'
Large ship capacity be 'L'

Form question -- small cargo ship is loaded in 2.5 hours, the rate at which the small ship loaded is S/2.5
-- large cargo ship is loaded at double the rate in X hours, the rate at which the large ship is loaded is L/x

Also, from question -- a large cargo ship is loaded at double the rate , so L/x = S/2.5 *2
L = S * X* 2/5 *2
L= S *(4X/5)
Hence 'D'

Volume (Small): R*T =2.5r
Volume (Big): R*T = X*2r
Big/Small = 20Xr/25r =4X/5. Answer is D.
