Seven men, A, B, C, D, E, F and G are standing in a queue in that orde...
A person can see caps of all persons standing in front of him but can't see his own cap and caps of persons standing behind him.
Given that E wears indigo cap.
D is able to see in front of him green and blue, but not violet which means the people in front of D i.e., A or B or C wore green or blue and people after D and including himself i.e., D or E or F or G wore violet. E can see violet and yellow but not red.
Clearly, D is wearing violet cap and A/B/C wore green/blue/yellow not necessarily in that order. G can see caps of all colours other than orange which means he is the last person in the row, he can see all caps except his. So, we can say G is wearing orange cap.
So, we can summarise all this information in a table

Finally, we are left with red cap which means F is wearing it.

Seven men, A, B, C, D, E, F and G are standing in a queue in that orde...
Given Information:
- There are seven men (A, B, C, D, E, F, and G) standing in a queue in that order.
- Each man is wearing a cap of a different color: violet, indigo, blue, green, yellow, orange, and red.
- D can see green and blue in front of him but not violet.
- E can see violet and yellow but not red.
- G can see caps of all colors other than orange.

Analysis:
To determine the color of the cap worn by F, we need to consider the information given about the visibility of colors by D, E, and G.

1. D can see green and blue in front of him but not violet.
- This means that the cap worn by D cannot be green or blue.
- D can see the caps of A, B, and C but cannot see the cap of G.

2. E can see violet and yellow but not red.
- This means that the cap worn by E cannot be violet or yellow.
- E can see the caps of A, B, C, D, and F but cannot see the cap of G.

3. G can see caps of all colors other than orange.
- This means that the cap worn by G cannot be orange.
- G can see the caps of A, B, C, D, E, and F.

Solution:
Considering the above information, we can deduce the following:

- D can see the caps of A, B, and C but not G.
- E can see the caps of A, B, C, D, and F but not G.
- G can see the caps of A, B, C, D, E, and F.

Since G can see the caps of D, E, and F, it means that the cap worn by F must be a color that is visible to G.

From the given options, the only color that is not visible to G is orange. Therefore, the color of the cap worn by F must be red.

Hence, the correct answer is option 'A' - Red.

Similar JEE Doubts

Crystal field theory views the bonding in complexes as arising from electrostatic interaction and considers the effect of the ligand charges on the energies of the metal ion d-orbitals.In this theory, a ligand lone pair is modelled as a point negative charge that repels electrons in the d-orbitals of the central metal ion. The theory concentrated on the resulting splitting of the d-orbitals in two groups with different energies and used that splitting to rationalize and correlate the optical spectra, thermodynamic stability, and magnetic properties of complexes. This energy splitting between the two sets of dorbitals is called the crystal field splitting D.In general, the crystal field splitting energy D corresponds to wavelength of light in visible region of the spectrum, and colours of the complexes can therefore be attributed to electronic transition between the lower-and higher energy sets of d-orbitals.In general, the colour that the we see is complementry to the colour absorbed.Different metal ion have different values of D, which explains why their complexes with the same ligand have different colour.Similarly, the crystal field splitting also depends on the nature of ligands and as the ligand for the same metal varies from H2O to NH3 to ethylenediamine, D for complexes increases. Accordingly, the electronic transition shifts to higher energy (shorter wavelength) as the ligand varies from H2O to NH3 to en, thus accounting for the variation in colour.Crystal field theory accounts for the magnetic properties of complexes in terms of the relative values of and the spin pairing energy P. Small values favour high spin complexes, and large Dvalues favour low spin complexes.Which of the following statements is incorrect?
