Input : 22 8 erunets 12 erutely erusker 18 erutify erusque 26 14 erutism
Step I : erunets 22 12 erutely erusker 18 32 erutify erusque 26 14 erutism
Step II : erusker erunets 22 erutely 18 erutify 32 72 erusque 26 14 erutism
Step III: erusque erusker erunets 22 erutely 18 32 72 98 erutify 26 erutism

Solutions

Sol. (1 -5): From the given statements, R% who is graduated from UGI sits opposite to the one who sits at the immediate left of R©. RΩ sits just behind the R*. So, we have two possible cases i.e. case1 and case2. The one who is graduated from KPJ sits just behind the R©. The one who is graduated from KPJ sits just behind the one who sits second to the left of the one who is graduated from UPI.

RΩ sits at the immediate right of R&. R& sits just behind the one who is graduated from UGI. So, case 2 gets eliminated here. The persons who are graduated from FPT and HNB are sitting on the same table and sit opposite to each other which means these persons are sitting on the inner table. R& is not graduated from FPT. The one who is graduated from HTS sits at the immediate left of the one who is graduated from LPU which means R@ is graduated from HTS, R© is graduated from LPU and RΩ is graduated from NIT. R$ is not graduated from FPT which means R$ is graduated from KPJ and R# from FPT. So, the final arrangement is:
\

Q(6- 10):  The machine rearranges one number and one word in each step. Words are arranged in alphabetical order from right to left whereas numbers are arranged in an order of half of the square of the number starting from the smallest number and the number arrangement takes place from the 7th position.
Input: 8 10 unroffs 2 unroots 12 unrobed unrolls 6 unrobes
Step I : unrobed 8 10 unroffs unroots 2 12 unrolls 6 unrobes
Step II : unrobes unrobed 8 10 unroffs 2 72 unroots unrolls 6
Step III: unroffs unrobes unrobed 8 10 2 72 18 unroots unrolls
Step IV: unrolls unroffs unrobes unrobed 10 2 72 18 32 unroots
Step V: unroots unrolls unroffs unrobes unrobed 2 72 18 32 50
