In a newly launched video game ‘Shoot At Sight’, each player is supposed to shoot at targets on the screen. For each hit, the score of the player gets doubled while for each miss, his score gets halved. Each player is given 10 shots at the targets. Each player starts with 100 points in his account initially. The game is over as soon as a player uses all his 10 shots. Two friends, Jai and Viru, played the game and finished with a total of 6,400 and 1,600 points respectively.
What could be Viru's total points after his 8 th shot?At his usual rowing rate, Rahul can travel 12 miles downstream in a certain river in 6 hr less than it takes him to travel the same distance upstream. But if he doubles his usual rowing rate for 24 miles round trip, the downstream 12 miles would then take only 1 hr less than the upstream 12 miles. What is the speed of the current in miles per hour?
