Question

Saurabh and Ashwini work for a MNC. Two of their regional head offices are located in Brazil in Rio De Janeiro and Manaus, respectively. Both of them have to contact either of the head offices constantly. As they have to adjust timings according to their head offices, find out their corresponding timings in India, if they work according to office timings in Brazil i.e 10am. to 5 pm. 

Answer 1

1. Let's assume Saurabh is coordinating with Rio De Janeiro’s head office and Ashwini is coordinating with the head office of Manaus. 
2. Brazil has four time zones. It is behind the GMT by 2, 3, 4 or 5 hours. 
3. Rio De Janeiro is in the 2nd time zone which is 3 hours behind GMT (GMT-03) and Manaus is the 3rd time zone which is 4 hours behind GMT (GMT-04).
4. Now, the time difference between GMT and 1ST is of 5 hours 30 mins.
5. They have to make following adjustments :

Saurabh
Rio De Janeiro	GMT	IST
10 a.m.	1 p.m.	6.30 p.m.
5 p.m.	8 p.m.	1.30 a.m.

 

Ashwini
Manaus	GMT	IST
10 a.m.	2 p.m.	7.30 p.m.
5 p.m.	9 p.m.	2.30 a.m.

Rio De Janeiro is in the 2nd time zone which is 3 hours behind GMT (GMT-03) and Manaus is the 3rd time zone which is 4 hours behind GMT (GMT-04)
Corresponding timings in India Saurabh: 6.30 p.m. to 1.30 a.m. Ashwini: 7.30 p.m. to 2.30 a.m.
