1) If log 0.317=0.3332 and log 0.318=0.3364 then find log 0.319 ? Sol: log 0.317=0.3332 and log 0.318=0.3364, then log 0.319=log0.318+(log0.318-log0.317) = 0.3396 2) A box of 150 packets consists of 1kg packets and 2kg packets. Total weight of box is 264kg. How many 2kg packets are there ? Sol: x= 2 kg Packs y= 1 kg packs x + y = 150     .......... Eqn 1 2x + y = 264   .......... Eqn 2 Solve the Simultaneous equation; x = 114 so, y = 36 ANS :  Number of 2 kg Packs = 114. 3) My flight takes of at 2am from a place at 18N 10E and landed 10 Hrs later at a place with coordinates 36N70W.
