We will be solving interesting sets as a part of this series LRDI of the Day. I will be posting a video solution by the end of the day. You can keep a track of all the sets by clicking here: LRDI of the Day

#LRDIoftheDay #43 A tough one for today

Angry Masterji has assigned roll numbers 2, 3, 4, 5 and 6 to five of his students viz. Bhuvan, Banchod Das, Sameer, Hola and Bablu not necessarily in that order. He decides to do a fun activity while conducting roll calls and calls out a random number in a round and does this over seven rounds with a different number called in each round. The students who have a roll number that is the factor of the random number called answer with a ‘Yes’ and the ones who do not have a factor of the random number called answer with a ‘No’. The following facts are known:

i. The sum of the seven random numbers is 100 and each of them is greater than 2

ii. The sum of the numbers called in Round 1 and Round 2 is 30

iii. Angry Masterji does not call out the numbers 6 and 7

iv. Exactly one of the called numbers is less than 10

The table that is formed at the end of the activity looks as follows:

If the answer to any question cannot be determined uniquely, type 0 in the text box.

1. What is the number called in Round 3?

2. What is the number called in Round 4?

3. What is the number called in Round 5?

4. What is the number called in Round 6?

The solution
