Question

‎ ‎ ‎ ‎ ‎ ‎ A certain mobile-phone video game consists of four puzzles, which players can attempt in any order. No puzzle is part of another. The puzzles, from easiest to most difficult, are: • Forest • Desert • Mountain • Ocean ‎ ‎ ‎ ‎ ‎ ‎ The puzzles require players to use items of various types. The player begins the game with exactly 3 items, one of each of the following types: • Compass • Bottle • Rope ‎ ‎ ‎ ‎ ‎ ‎ Each of a player’s items can be either used once in solving a puzzle or exchanged once for coins —the in-game currency—but not both. Coins are used to purchase items. The player begins the game with 0 coins.‎ ‎ ‎ ‎ ‎ ‎ To solve each puzzle, a player is required to use one item of a specific type and a number of additional items of any type. Solving each puzzle earns the player a reward of coins. The complete list of requirements and rewards is shown in the table. https://gmatclub.com/forum/download/file.php?id=76090‎ ‎ ‎ ‎ ‎ ‎ For each item type, the table shows the purchase price and exchange value per item. A player can purchase multiple items of a given type provided he or she has enough coins. For example, a player with 20 coins can purchase 2 Clocks. https://gmatclub.com/forum/download/file.php?id=76091 https://gmatclub.com/forum/download/file.php?id=81995 https://gmatclub.com/forum/download/file_private.php?id=76086 https://gmatclub.com/forum/download/file_private.php?id=76087 https://gmatclub.com/forum/download/file_private.php?id=76087 https://gmatclub.com/forum/download/file_private.php?id=76089 https://gmatclub.com/forum/download/file_private.php?id=76088 2024-04-17_12-44-45.png 2024-04-17_12-46-33.png GMAT-Club-Forum-y2eelufy.png

Can someone please explain how to proceed with the first question? The other two were quite straightforward comparatively.

ShubhamSS28 · Answer

For first question

We are given about new puzzle i.e, Cave puzzle that requires players to use 1 Lantern and 4 additional items of any type.
Further, we are asked about  minimum number of coins a player who currently has no items  would have to spend to purchase all of the items necessary to solve the Cave puzzle ? 
Refer item values table, purchase price per item column :
1 Latern - 15 Coins
4 Items of any type (it can be same item type as well but number of coins has to be min.)
So purchase 4 items either of Clock/Mirror = 40 coins (10 coin per item)

So min. number of coins required = 15+40 = 55

PRAGATIOSTWAL · Answer

Thank you  ShubhamSS28  for the explanation.
I was interpreting one of the statements as we can't purchase more than 1 item for any item type in any puzzle, hence, the mistake.

Jyotwa · Answer

kindly explain answer of 2nd question

zlishz · Answer

hi  Jyotwa 
In the 2nd question, we have to 'select Yes if the player must have purchased at least one such item in the game. Otherwise, select No.'

Refer to the tab 'Game Elements', here we are told that,
  The puzzles require players to use items of various types. The player begins the game with exactly 3 items, one of each of the following types:
• Compass
• Bottle
• Rope

That means the player starts with these items and can exchange it to get coins and further buy other items.
Therefore, the player need not necessarily buy a Compass, so a  No for Compass.

Now refer to the tab ' Puzzle Details' -> Required Types, here we can see that none of the Puzzles require a Clock, so  No for Clock . 
And the player needs a Boat for the Puzzle Ocean, so a player who has completed all the 4 puzzles must've purchased a Boat so,  Yes for Ocean .

Dbrunik · Answer

if one has 40 points to start, and sells 30 to buy the boat, you now have 10 points via the compass, and only two items. if you exchange the compass, you can only buy one clock or one mirror.

how do you get to 3 additional items for Ocean?

ReetArora · Answer

but in 2nd question compass is also necessary for solving puzzle forest. Then why is it NO for that.

Hitesh0701 · Answer

He already has compass that's the reason why he will not purchase that.
He doesn't have boat, so he will buy that boat

Carlosgmdn · Answer

For the question of each of the following statements, the one that says these items alone are sufficient to complete the ocean I put yes because, with this 3 items I can solve the other puzzles and buy enough stuff to finish the ocean puzzle, however, the answer is "no". Where am I wrong?

Pray2K · Answer

In case of Q2. The question asks which item is a "must" purchase.

In case of the Puzzles requiring Additional Items, there is no specific requirement for purchasing only Clock. Thus its a "NO".

nishantkakani · Answer

I did the same mistake, I think the question is looking for us to answer for the items given in the start itself. Purchasing a new item, in the case a boat and the required items for the ocean part of the game, is considered as not using the initial items  only.  Thats what i could make from it.

himssss29 · Answer

How is the exchange value of these 3 items 40 coins? 
Isn't it 5+10+15= 30?

Jay2050 · Answer

The three items to be exchanged are:
Compass – 10 coins
Bottle – 15 coins
Rope – 15 coins

Total: 40 coins

Yes	No
		The total exchange value of these items is 40 coins.
		Exchanging the Bottle and the Rope will provide the player with sufficient funds to purchase 1 Boat.
		These items alone are sufficient to solve the Ocean puzzle.
