Official Explanation

RO1

The task in this question is to find a characteristic held by fewer than half of a certain subset of the cell phones in stock at the store.

The first characteristic listed (A), are touch-screen-only phones, is held by fewer than half of all the phones in stock but not necessarily of any subset of those phones—since it is possible that more touch-screen-only phones than dial pad phones are available to be sold at a discounted price.

The second characteristic (B), have screens 8 cm or larger, is held by fewer than half the dial pad phones, but that subset is not one of the options available. It is not possible to make a determination about the third characteristic (C), are purchased without a service contract, because there is no information about purchases—only the phones that are available at the store.

The fourth characteristic (D), are available at a discounted price with a service contract, is held by most phones in stock. There is no indication that it is true of fewer than half of any subset.

The fifth characteristic (E), are packaged with fewer than two accessories, is held by fewer than half dial pad phones and also true of fewer than half touch-screen only phones. It is not necessarily held by fewer than half of any subset of those phones, however. (For example, most touch-screen-only phones have screens 8 cm or larger, but it does not follow that fewer than half of those phones are packaged with fewer than two accessories; more than half of them could be packaged this way, and that characteristic would still be held by less than half of all touch-screen-only phones.) Therefore, the subset that fits the criteria is are touch-screen-only phones (blank #1), and the characteristic that is true of fewer than half of those phones is are packaged with fewer than two accessories (blank #2).

The correct answer is are touch-screen-only phones.

RO2

As explained in the analysis of RO1, the only characteristic listed that is true of fewer than half touch-screen-only phones is are packaged with fewer than two accessories.

The correct answer is are packaged with fewer than two accessories.

1) are touch screen-only phones have screens 8 cm or larger

2) are purchased without a service contract

3) are available at a discounted price with a service contract

4) are packaged with fewer than two accessories

Among all four statements, the one with service warranty can't be used as we don't know which of the mobile phone is more (more than 8cm screen size or less than 8cm screen size)

Statement 2: We know most are sold with service contract. So second statement is invalid because we have contradictory information as such given in passage.

Statement 3 : are available at a discounted price with a service contract. Let say this is the first statement what could be fewer than half in the other statement? Has fewer than 2 accessories? But what kind of phone it is? Information gap is in there.
Are touch screen phone with 8cm screen or larger. But are they the least? Keypad ones could be in least number. No determining factor.
Hence statement 3 is invalid.

Among last two, 1&4 statement.
We can't use the statement "are packed with fewer than 2 accessories. What is packed? Which type?
Hence first statement has to statement 1, and later is statement 4

Now checking validity. We know the shops have both phones. Some are 8cm screen touch phones rest are other. We don't have to check quantity, hence valid.
Fewer than half have less than two accessories, is valid because it's stated that most are packed with two accessories.

Hence the answer is,
of those that "are touch screen-only phones have screens 8 cm or larger", fewer than half "are packaged with fewer than two accessories".

P.S. SajjadAhmad kindly edit the OA, the statement 1 is til 8cm or larger.
Thank you.

Given the information regarding the cell phones in stock at the store, it follows that, of those that "are touch screen-only phones" fewer than half are are packaged with fewer than two accessories,since it's given that most of the touch screen phones are packaged with 2 or more than 2 accessories.

Hi,

What it means by ‘Most are sold at a discounted price if purchased with a new or renewed service contract’?
I understand out of phones purchased with a new contract or renewed service contract, most (>50%) of them (phones purchased with a new contract or renewed service contract) are sold at discount.
Example:
Total phones in the store are 100
50 are purchased with a new or renewed service contract, then more than 25 will be sold at a discounted price.
It does not mean that more than 50 (out of 100) are sold at a discounted price.
Is my above understanding correct?
But if we look at the explanation( from OG) of answer choice ‘D’. The explanation says that most of them are at a discounted price.

It is not possible to make a determination about the third characteristic (C), are purchased without a service contract, because there is no information about purchases—only the phones that are available at the store.
