Wells Fargo Coding deductive logic Problems with Solutions Quiz-1

Call A the event that Ramu is present in the photo. Call B the event that his brothers are present. We are given that A→B. So, we know the identities of three of the people in that photo i.e. Ramu and his three brothers.

But, we are told that the photo already has three people (Ramu’s parents with their daughter). This would mean, there is a total of six people in the photograph. This is impossible as it is clearly stated that there are only five people in the photo. Thus, Ramu cannot be in the photo.

Hence, option B is the correct choice.

We have from first two statements: ‘if the contract is valid then X would be bankrupt.’

Statement 3 could be re-written as ‘If he goes bankrupt, then the bank will not loan him the money.’ From above two statements, we have: If the contract is valid, then the bank will not loan him the money. This is reflected in option B.

Hence, option B is the correct choice.

If W: Doing well in CAT

X: Doing well in JMET

Y: Getting admission in IITs or IISc.

Z: Getting admission in IIMs

Then the given statements can be written as:

Statement (i): W→X
Statement (ii): X→Y
Statement (iii): W→ Z which also implies Z→W
Consider option A: Doing poorly in CAT implies doing poorly in JMET.

This statement can be written as: W→ X
∴ This statement cannot be logically deduced from the given statements.

Consider option B: Good CAT result ensures that one gets an admission into the IIMs

This statement can be written as: W→Z
∴ This statement also cannot be logically deduced from the given statements.

Consider option C: Admissions to the IITs or IISc may mean that one has done well in CAT.

This statement can be written as: Y→W
This statement also cannot be logically deduced from the given statements.

Consider option D: Anyone getting admissions in one of the IIMs is guaranteed to get admission in one of the IITs or IISc.

This statement can be written as: Z→Y
∴ This statement can be logically deduced from the given statements.

Hence, option D is the correct choice.

From condition (3), B and G are in different boats.

∴ If F and B are in one boat, G is in the other boat.

Hence, option A is the correct choice.

From condition (4), the maximum number of persons in one boat can be four only.

∴ There must be at least three people in the complete list of people who must be sitting in either boat.

Hence, option D is the correct choice.

From the given information:

If someone likes task B, he definitely likes E and does not like C while he may or may not like task A.

If someone likes task C, he definitely likes D and does not like E but definitely likes F.

If someone likes task D, he definitely likes F and may like E or C but not both.

∴ If Amit enjoys D, that means he may or may not like C.

Hence, option A is the correct choice

Balvinder likes B. So, he definitely likes E and thus, he definitely does not like task C.

Hence, option B is the correct choice.

It is known that if someone likes task C, then he definitely does not like task E.

∴ Chetan definitely does not like task E. So, option D is false.

Hence, option D is the correct choice.

Option A is incorrect because all those who like task E do not like task C.

Someone who likes task F may or may not like task A. So, option B is incorrect.

As all those who like task E do not like task C, but only some of those who like task E also like task A, we can say that those who like the task A may or may not like the task C. So, option 3 is correct.

Option D is also incorrect because all those who like task B like task E and may or may not like task D.

Hence, option C is the correct choice

Let, A be the event that the sky is red and B the event that rain is forecasted.

We have been given that A→ B, and hence that B→ A
Now, we have been given that the rain proved the forecast wrong. Thus, the forecast must have been that there would be no rain.

We have no expression with B on the LHS.

Thus, we cannot say anything about the colour of the sky on the basis of the fact that rain was not predicted.

Hence, option C is the correct choice.
