Which of the following combination is
true? Study the following information carefully and answer the below questions Six persons- R, S, T, U, V, and W are sitting on the circular table facing the center. They are using different types of laptops- Apple, Lenovo, Dell, Samsung, Asus, and HP but not necessarily in the same order. U sits second to the left of the one who uses HP laptops. The one who uses HP laptops and the one who uses Dell laptops are immediate neighbors. S sits opposite to the one who sits immediate right of R. S neither uses HP nor Dell. The one who uses Apple sits second to the left of R. The one who uses Samsung sits immediate left of the one who uses Asus. U neither uses Asus nor Lenovo. Either S or V uses Lenovo. W does not use Dell.Solution
We have, U sits second to the left of the one who uses HP laptops. The one who uses HP laptops and the one who uses Dell laptops are immediate neighbors. From the above condition, there are two possibilities.
Again we have, S sits opposite to the one who sits immediate right of R. S neither uses HP nor Dell. From the above condition, there are four possibilities.
Again we have, The one who uses Apple sits second to the left of R. The one who uses Samsung sits immediate left of the one who uses Asus. U neither uses Asus nor Lenovo. From the above condition, Case2, case1a, and case2a get eliminated.
Again we have, Either S or V uses Lenovo. W does not use Dell. From the above condition, case1 shows the final arrangement
