Directions for next 5 questions:
Five friends, Achal, Jitesh, Karthik, Pratyush and Tapish, are trying to build a tower using blocks. Each person arranges certain number of blocks on top of existing blocks. Every day at least 4 persons play this game.
It is known that:
- On any day if both Achal and Jitesh arrange blocks, Jitesh puts 1 block less than Achal.
- On any day if both Jitesh and Karthik arrange blocks, Jitesh puts 2 blocks more than Karthik.
- On any day if both Pratyush and Karthik arrange blocks, Pratyush puts 3 blocks more than Karthik.
- On any day if both Pratyush and Tapish arrange blocks, Pratyush puts 6 blocks more than Tapish.
- On any day if both Tapish and Achal arrange blocks, Achal puts 5 blocks less than Tapish.
The following graph provides, the height of the tower (in terms of number of blocks) at the end of each day.
How many blocks were arranged by Tapish across all 5 days.
What is the least number of blocks arranged by any of the five friends on any of the 5 days.
Who among the 5 friends arranged blocks on maximum number of days?
- (a)
