If U, P, and R are in holes 5, 6, and 7, respectively, which of the following must be true ?
Each of six pegs - P, Q, R, S, T and U - is placed in a different one of seven holes numbered consecutively 1 through 7 from left to right. The holes are evenly spaced and arranged in a straight line. The placement of the pegs is subject only to given conditions:
1. The distance separating P from Q must be the same as the distance separating R from S;
2. T must be in a hole immediately adjacent to the hole that U is in;
3. The left most hole cannot be the hole that is left empty.
সঠিক উত্তর: Option B
Solution:
| 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Q | S | Empty | T | U | P | R |
কারণ, (1) নং শর্ত অনুযায়ী দেখুন P থেকে Q যে দূরত্বে, R থেকে S ও সেই একই দূরত্বে আছে ।
আর (2) নং শর্তানুযায়ী 4 নং গর্তে T কে রাখা হলো । তাই সঠিক উত্তর b).
