Thread: Logical Reasoning Question

Will anyone be kind enough to help me comprehend the Questions 46 and 47 in the attached (Bitmap image) question below:


I attempted Question 45:

I multiplied the number of larger boxes for each ship type by 4 and attempted to subtract 12 from each.

I deduced that the Navy Ship can carry 12 smaller boxes with the least amount of room left over:

5 x 4 = 20 - 12 = 8-room left over in terms of smaller boxes)

Hi KayPee!

Question 46: To transport 72 smaller boxes, you need to have space for 18 large boxes.
Since you're not supposed to have space left, can you find a combination of ships that together carry exactly 18 large boxes?

Question 47: You need 28/4=7 large boxes.
Which combinations of ships can you find that carry at least 7 boxes?

So for Question 46 is the answer 3?

since:

Tanker-2
Tug Boat-10
Navy Ship-5
Sail Boat-1

OR

Tanker-2
Submarine-15
Sail Boat-1



For Q.47:

Tanker-2 Boxes and Navy Ship-5 Boxes
$100-Answer?

Yep!

Thanks

What about Q.47:

Tanker-2 Boxes and Navy Ship-5 Boxes
$100-Answer?

Can you find more combinations?

Sorry are you referring to question 47?

I think the cheapest must be the the Tug Boat-$95?

Right on!

One more thing please.Was my answer to Q.45 right?

the Navy Ship can carry 12 smaller boxes with the least amount of room left over:

5 x 4 = 20 - 12 = 8-room left over in terms of smaller boxes)

Yes it was.
