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. What is the local time when my plane landed? Options: a)6:00 am b) 6:40am c) 7:40 d) 7:00 e) 8:00 Sol: The destination place is 80 degree west to the starting place. Hence the time difference between these two places is 5 hour 20 min. (=24hr*80/360). When the flight landed, the time at the starting place is 12 noon (2 AM + 10 hours). Hence, the time at the dest...

Below are three problems based on the concept of mixtures in some ratio. Question 1 A certain box of health drink powder is obtained by mixing the makers as 3 parts of milk powder with 5 parts of energy powder. If 2 kg of the mixture is needed and the individual makers can be purchased only in one kg or half kg box. What is the least amount of makers, in kg's, that must be purchased in order to measure out the portions needed for the mixture? a)2kg b)3kg c)4.5kg d)2.5kg Answer : d)2.5kg Solution : Step 1) "A certain box of health drink powder is obtained by mixing the makers as 3 parts of milk powder with 5 parts of energy powder. " You should think: 3 parts of milk powder, 5 parts of energy powder sums to a total of 8 parts. More specifically, 3/8 of the mixture is milk powder and 5/8 of the mixture is energy powder. Step 2) "If 2 kgs of the mixture is needed and the individual makers can be purchased only in one kg or half kg cans" So w...

Below are three questions on numbers on concepts dealing with odd and even and a new class called "even-odd" numbers. Question 1 If n is an even-odd number then which of the following must be false? (A number is called "even-odd" if it is halfway between an even integer and an odd integer.) a) n/2 is not an integer b)(2n) 2 is an integer c)4n is an odd integer d)none of these Answer : c)4n is an odd integer Solution: A number is called "even-odd" if it is halfway between an even integer and an odd integer. For example, consider an even integer 10 and an odd integer -5. Number halfway between them will be (10 - (-5)) / 2 = 7.5. Here 7.5 is an "even-odd" number. i.e., an even-odd number will be in the form x + 1/2 = x.5 where x is any integer. Let us see with each option: Consider option a : Since n is a fraction number then n/2 is also a fraction. i.e., n/2 is not an integer. Hence option a is true. Consider option b :...
