Since the worker, carried jugs of liquid soap(4 jugs/trip)
In 17 trips, he would carry 68 jugs of liquid soap.

Since he can fill 7 jugs in a carton, he will need to add 2 more jugs
such that he has 70 jugs and he can fill the jugs in 10 cartons.

Hence he needs 2 jugs(Option B) such that the last partially filled carton is full.

Start only with how many jugs total the worker carries in 17 trips (i.e. ignore the 7 per carton for now - that's crazy-making).

4 jugs per trip * 17 trips means s/he carried 68 jugs.

Then figure out how many cartons have been filled, and if there are any partly filled cartons.

If there must be 7 jugs in each carton, divide 68 by 7 to get the number of cartons that are full and whatever is left over.

$$\frac{68}{7}$$= 9 + remainder 5.

So 9 cartons are full of 7 jugs, and one carton is has only 5 in it. It needs 2 more.

Good questionn. A miss in the reading and anyone could end up making the mistake that I made. this question is not tricky in calculation or logic but in paying attention to detail. We need to keep in mind that the question is asking how many jugs are needed to fill the last partially filled carton. meaning thereby that it is not asking for the remainder after 68 has been divided by 7, but how many jugs will be needed to complete another carton.

After 17 trips, the worker has carried 17 x 4 = 68 jugs.

From those 68 jugs, 68/7 = 9 cartons have been filled, with 5 extra jugs remaining. So, the worker needs one more trip to carry 2 more jugs to fill the partially filled carton with those 2 jugs.

each trip fills 4/7 of carton
(17*4)/7 leaves a remainder of 5
7-5=2 more jugs needed

The worker has finished 17 trips.
Hence the number of jugs transported = 17*4 = 68.

But the carton can accommodate 7 jugs. So 68/7. This will give a remainder 5.
Now to fill the last partially filled carton(currently having 5) we can add 2 more.

Hence B

Hi All,

We're told that a worker carries 4 jugs of liquid soap per trip and that the jugs are packed into cartons that hold 7 jugs each. We're asked for the number of jugs needed to fill the last PARTIALLY-filled carton after the worker has made 17 trips.

With those first 17 trips, the worker would have transported (4)(17) = 68 jugs of soap.

Since each carton holds 7 jugs, those 68 jugs would lead to 9 FULL cartons (totaling 63 jugs) and a 10th carton that has 5 jugs in it. Thus, 2 more jugs would be needed to fill that final carton.

What indicates that the worker made 17 trips while carrying just 4 jugs?
The question only specifies that he made 17 trips while carrying them in cartons.

SwatiL - The worker takes 4 Jugs from production area to the packing area in every trip. The packing area is where the jugs are then placed in the carton.

after 17 trips, he would have taken 68 jugs, but the carton's capacity is 7 jugs, implying that in the last carton there is room for 2 more jugs (the closest multiple of 7 is 70).
