Quantitative:

Q1. If g (0)=g (1)=1 And g (n)= g (n-1) + g (n -2)
find g (6);

Sol:

G(0) = 1
G(1) = 1
G(2) = G(1) + g(0) = 2
G(3) = g(2) + g(1) = 3
G(4) = g(3) + g(2) = 5
G(5) = g(4) + g(3) = 8
G(6) = g(5) +g (4) = 13

Q2.A plane moves from 9 N40 E to 9 N40 W. If the plane starts at 10 am and takes 8 hours to reach the destination, find the local arrival time?

ANS:
The time is calculated on the basis of longitude.
(Based on sunrise) Sun rises earlier in calcutta than in Mumbai. The 40 degrees east and 40 degress west are calculated form 0 degrees. The plane has travelled westwards by 40+ 40 = 80 Degrees. (WEST) For each degree there is a difference of 4 Minutes. The difference in timings is 320 Minutes behind. As per the starting point time 10.00 AM the flight should have reached at 6.00 PM.
Reducing 320 Minutes from it we get 12.40 PM local time at the destination
