According to the given information, A works in B2K Solutions.
To find out who works in B2K Solutions, we need to analyze the given information:
'A' has a Sonata watch and the one who works in C Cube Solutions paid Rs. 8000 for his watch.
'C' is not working in B2K Solutions or Global Solutions and he did not pay Rs. 14000 for his watch. The cost of Sonata watch is neither Rs. 15000 nor Rs. 10000.
The person working in ANZ has an Esprit watch. 'B' does not have an HMT watch and does not work in ANZ.
'D' works in Jupiter and did not pay Rs. 10000 or Rs. 6000 for his watch. 'E' does not work in MARS and the cost of a Citizen watch is Rs. 6000.
The person who has a Fossil watch works in Jupiter. HMT watch costs Rs. 14000 and the person who has a Titan watch works in C Cube Solutions.
The person who works in Global Solutions has a Citizen watch, but he is not 'F' or 'B'. 'A' does not work in MARS.
From the given information, we can conclude:
'B' works in ANZ because the person working in ANZ has an Esprit watch and 'B' does not have an HMT watch.
'C' is not working in B2K Solutions or Global Solutions, so 'C' cannot be the answer.
'D' works in Jupiter but paid neither Rs. 10000 nor Rs. 6000 for his watch. 'E' does not work in MARS and has a Citizen watch, which means 'E' cannot work in B2K Solutions.
'F' works in Global Solutions, and from the given information, the person who works in Global Solutions has a Citizen watch, so 'F' cannot work in B2K Solutions.
Therefore, 'A' works in B2K Solutions.
