Question
Six persons, F, G, H, I, J and K, sit in a row and face
in north direction. Only two persons sit to the right of J. I sits immediate left of K. Neither F nor I sits at an extreme end. G sits immediate left of H, who doesn't sit at an extreme end. Who sits second to the right of F?Solution
Only two persons sit to the right of J. I sits immediate left of K. Neither F nor I sits at an extreme end. G sits immediate left of H, who doesn't sit at an extreme end. We get J sits 4th from the extreme left end. I sits immediate right of J or second to the left of J. K sits second to the right of J or immediate left of J. G, H, F, I and K sits first, second, third, fifth and sixth from the extreme left end of the row. Therefore, the sitting arrangement is given below: GÂ Â Â Â Â Â Â Â HÂ Â Â Â Â Â Â Â FÂ Â Â Â Â Â Â Â Â JÂ Â Â Â Â Â Â Â Â IÂ Â Â Â Â Â Â Â Â Â K
