  6. 1. In a cricket match, the "man of the match" award is given to the player scoring the highest number of runs. In case of a tie, the player (out of those locked in the tie) who has taken the higher number of catches is chosen. Even thereafter if there is a tie, the player (out of those locked in the tie) who has dropped fewer catches is selected. Aakash, Biplab and Chirag who were contenders for the award dropped at least one catch each. Biplab dropped 2 catches more than Aakash did, scored 50, and took 2 catches. Chirag got two chances to catch and dropped both. Who was the "man of the match? A. Chirag made 15 runs less than both Aakash and Biplab. B. The catches dropped by Biplab are 1 more than the catches taken by Aakash. 2. Four friends, A, B, C and D got the top four ranks in a competitive examination, but A did not get the first, B did not get the second, C did not get the third, and D did not get the fourth rank. Who secured which rank? A. Neither A nor D were among the first 2. B. Neither B nor C was third or fourth.


  7. 3. The members of a local club contributed equally to pay Rs.600 towards a donation. How much did each one pay? A. If there had been five fewer members, each one would have paid an additional Rs.10. B. There were at least 20 members in the club, and each one paid no more than Rs.30. 4. A family has only one kid. The father says after "n" years, my age will be 4 times the age of my kid. The mother says after "n" years, my age will be 3 times that of my kid. What will be the combined ages of the parents after "n" years? A. The age difference between the parents is 10 years. B. After "n" years, the kid is going to be twice as old as she is now.


  8. 3. The members of a local club contributed equally to pay Rs.600 towards a donation. How much did each one pay? A. If there had been five fewer members, each one would have paid an additional Rs.10. B. There were at least 20 members in the club, and each one paid no more than Rs.30. Solution: From statement A, Let there are x members in the club. 600 600 = 10 x = 20. Statement A alone is sufficient. From statement B, We get there were at least 20 members in the club and each one paid no more than Rs. 30. The different possibilities for can be 30 members x 20 rupees Rs. 600 40 members x 15 rupees Rs. 600 60 members x 10 rupees Rs. 600 and so on. Statement B alone is not sufficient. Hence, option 1.


  9. 4. A family has only one kid. The father says after "n" years, my age will be 4 times the age of my kid. The mother says after "n" years, my age will be 3 times that of my kid. What will be the combined ages of the parents after "n" years? A. The age difference between the parents is 10 years. B. After "n" years, the kid is going to be twice as old as she is now. Solution: From statement B, k+ n 2k Substituting equation (v) in equation(i), we get, f - m 2n Substituting equation (v) in equation (iv), we get, f+ m 14n 2n : The value of n is not known. We cannot find the combined age of parents. Statement B alone is not sufficient. Hence, option 1.
