From 3, 4, 5, 6, 7, 8 From 6 and 10 The highest floor which Shilpa and Ritu shop from is the Dollar Store. Shilpa shops only till fifth floor and not beyond it. Twice Ritu shops from floor adjacent to the floor from which Shweta shops and, Shweta does not shop from electronics but Ritu does. We also know that Ritu shops from 5^thfloor along with Mala and Shilpa. Ritu can only shop till 5^thfloor. Thus Ritu does not shop from seventh floor. Also, Shweta shops from fifth floor (condition 3). Mala shops from 4 departments from 4 different supermarkets such that out of those four supermarkets, 3 are located on 3 consecutive floors. Mala does not shop from third floor. And for once, Shweta and Mala shop from the same supermarkets. Thus, Mala definitely shops from 6^thfloor. Now Mala can either shop from 7^thfloor or from 4^thfloor. Hina shops for Electronics from Fresh n Easy along with Shweta shopping in a different department. Also, Shweta shops from second floor. Thus, Hina shops electronics from 2^ndfloor which is Fresh n Easy. Also, both Ritu and Hina shop in Electronics departments of two different supermarkets such that the one from which Ritu shops for electronics is located immediately above the one from which Hina shops for Electronics. Sugandha but not Mala shops from Fresh n Easy. Renu shops fashion from Fresh n Easy. Thus, Shweta shops Home décor from Fresh n Easy and Fashion from the dollar store. Sugandha and Mala each shop from four supermarkets and thrice from the common supermarkets. We know from the table that Mala but not Sugandha shops from floor 5. Thus, at rest all supermarkets from where Mala shops, Sugandha also shops. Renu, Meera and Tina shop together on two floors, once with Hina and once with Ritu but not on first floor. The floor cannot be 1(given) 2(already filled) 4 (given that Shilpa shops from 4^thfloor) 5(Mala, Shilpa etc on 5^thfloor) 6(Shweta, Mala, Sugandha on 6^thfloor) The floor can be 3 and 7. Thus, Hina shops from fashion department from floor 7. Sugandha and Mala each shop from four supermarkets and thrice from the common supermarkets. Sugandha and Mala shop together from three super markets and Sugandha and Mala shop without each other from one supermarket. Sugandha shops without Mala from Fresh n Easy Mala shops without Sugandha from The Dollar Store Thus, Now, from evey other super market from where Sugandha shops, Mala also shops and vice versa. Thus, Mala and Sugandha together shop from Big Bazaar (from table), Fourth floor (from table) and First floor (2,3,5,7 not possible). Neither Shweta nor Meera shop from electronics department (condition 3) Renu shops electronics from Store 99 and grocery from big basket and fashion from Fresh n Easy. Renu shops on third floor but never from The Dollar Store. Store 99 is situated above the Dollar store. Thus store 99 is on the 7^thfloor. Tina shops from Big Bazaar. The number of departments in which Meera shops is same as that of Tina but one less than that of Renu. From the table, Renu and Tina shop from 3 stores, but Renu shops in one store more than Tina. Thus Renu shops from 4 stores. Thus, Renu can shop from More. Also, Shilpa shops electronics form Easy day (given). Shilpa shops Home décor and fashion from consecutive floors. Mala shops from Home Décor department from the highest floor she visits. We know that the highest floor that Mala visits is floor 6. Thus Mala shops Home décor from floor 6.
