Read the following information carefully and answer the given questions. Komal covers 8 km distance by walking from point R to point S in south direction. She took a left turn and walks 9 km to reach at a point Q, she again took a left turn and covered 3km to reach at a point T. After walking 2 km towards the east from point T she reached at a point U, she took a final left turn and covered 3 km to reach at a point V. If point W is 1 km to the west of point Q, then what is the shortest distance between point V and point W?

Explanation

Shortest distance = √32 + 62 = 3√5 km. Solutions (56-60): (i)- By using given conditions, Y sits second to the right of X, who likes Emerald and X doesn’t sit at the extreme end. There are two possible cases- Case:1, X sits second to the left end and Case:2, X sits third to the left end. M sits to the immediate left of the person, who faces the person, who sits to the immediate right of the one who is sitting at the extreme left end of the other row. That means M sits middle of the row-1. The one who likes Coral sits second to the left of M. The one who likes Blue Topaz sits immediate right of the one who faces M. (ii)- P faces the one who sits second to the left of the who likes Blue Topaz. That means P sits immediate right of M. Q sits opposite to the one who sits third to the right of the one who likes Garnet. In case-1, Q sits immediate left of M and in case-2, there are two possibilities Q sits either immediate left of M or second to the left of M. U sits opposite to the person, who sits second to the right of N. Immediate neighbor of N likes Opal. By using these conditions case-2 will be eliminated and thus we continued with case-1. The one who likes Ruby sits second to the left of the one who likes Sapphire. That means the one who likes Sapphire sits extreme right end of the row-2. O doesn’t like Sapphire or Pearl. W doesn’t like Ruby or Black onyx. Hence, O likes Black onyx, M likes Pearl, Q likes Opal, W sits extreme left end and likes Sapphire and V likes Garnet. www.teachersadda.co.in | www.sscadda.com | www.bankersadda.com | www.adda247.com
