38. 10 identical coins are lying on a table having head 'H' face as the upper face. In one attempt, exactly four coins can be turned upside down. What is the minimum total number of attempts in which tail 'T' face of all the 10 coins can be brought to be the upper face?

Correct Answer: (a) 4
Solution:On the first attempt four coins are overturned. Now, six coins are left. In the next turn, four more are overturned. Now only two coins would be left, we take one more from the left over two coins and any three from the previously turned ones. Finally the left over coins and the three coins from the presiding step which have already been turned twice can be overturned. Thus, in four attempts, one can complete the process.

40. A and B take part in 100 meters race, where A beats B by 10 meters. To favour B, A starts 10 meters behind the starting line in a second 100 meters race, running at their earlier speeds. Which one among the following is true in view of the second race?

Correct Answer: (d) A beats B by 1 meter
Solution:When A goes 100 meters, then B goes 90 meters.

∴ Ratio of speed of A/B = 100/90 ⇒ A/B 10/9

∴ A starts 10 meters behind the starting line.

∴ A will cover the distance = 100+10= 110 meters

In same time and with same speed B will cover the distance

= 110/10 × 9 = 99 meters.

So, in new race A beats B by 1 meter.
