**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

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.

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.
