From the given information, we know that Amol, Shashi, Mandar and Reena received the video game, permume, calculator and sunglasses respectively. This means that Piyu received the sweater and we can then conclude that she gifted the jacket.
Since Mandar did not gift an electronic item, he could have gifted the fountain pen, the shirt or the jacket.
But we know that the shirt and the jacket were gifted by Amol and Piyu respectively.
So Mandar must have gifted the fountain pen.
We still need to figure out who gifted the cell phone and the I-Pod. Since we know that Shashi did not gift the I-Pod, Reena must have gifted the I-Pod and Shashi must have gifted the cell phone.
We can now match the friend’s name with the gift given and the gift received as follows:
Amol – Shirt – Video Game; Mandar – Fountain Pen – Calculator; Piyu – Jacket – Sweater; Shashi – Cell Phone – Perfume; Reena – I-Pod – Sunglasses.
Q.1 – (Ans.4) Piyu gifted the jacket.
Q.2 – (Ans.1) Amol and Mandar gifted the shirt and the fountain pen respectively (non-electronic items) and received the video game and the calculator respectively (electronic items).
Q.3 – (Ans.3) Reena gifted the I-Pod and received the pair of sunglasses in return.
Q.4 – (Ans.3) Only Amol and Mandar received electronic items. So option 1 is true. Shashi gifted the cell phone and received the perfume. So option 2 is true.
Reena gifted the I-Pod and in alphabetical order, she would appear second last. So option 3 is not true.
In alphabetical order, Piyu appears in the middle and she gifted the jacket and received the sweater in return. So option 4 is true.
