To check mutual exclusion we need to check that atmost one process should enter the citical section and when one process is in the critical section then other process cant enter, Here we can see that S1 and S2 are mutually exclusive cases. Checking manually also when one process is in the CS then other cant enter. Hence Mutual exclusion is satisfied. To check progress we need to check if two or more processes want to enter the CS then atleast one process should enter, also if the process can also enter individually if they are interested without interference of other [...]

The answer should be C) Bina. Here is a stepwise solution ->  1. China is sitting 3rd to the left of Dipa.(both facing inside) 2. Elina is not sitting adjacent to either of China or Dipa => only one position is left for her 3. One sitting between Dipa and Fiona will be facing outside => Dipa and Fiona need to have one empty place between them, this fixes the position of Fiona. 4. Gita sits 3rd to the right of Aina => it is not possible if we consider that Aina is facing inside(no empty place with a gap [...]

nth group starts with $(n-1)$$^{2}$ $+$ $1$ and ends with $n$$^{2}$ and every group consists $2n-1$ numbers $15th$ group starts with 196 and ends with $225$ $sum$ = $\frac{No of terms}{2}$ * $[first$ $term$+$last$ $term]$ = $\frac{29}{2} * [(196+1) + 225]$ = $6119$ [...]
