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...

Question 1 Four concentric circles are drawn with the radii at interval of X units. If the radius of inner circle is X units then the ratio of the area between the 4th and 3rd circles to the area between the 2nd and 1st circles is: a)1:2 b)2:1 c)4:3 d)7:3 Answer : d)7:3 Solution : Let X be the radius of inner(1st) circle. Given that the radii of the circles are at the intervals of X units. Then X + X = 2X, 2X + X = 3X, 3X + X = 4X are the radii of successive circles respectively. Now, the area of first circle = pi(X) 2 = pi x X 2 Area of second circle = pi(2X) 2 = 4 x pi x X 2 Area of third circle = pi(3X) 2 = 9 x pi x X 2 Area of fourth circle = pi(4X) 2 = 16 x pi x X 2 Then, the area between 1st and 2nd circles = (4 x pi x X 2 ) - (pi x X 2 ) = 3piX 2 br /> And the area between 3rd and 4th circles = (16 x pi x X 2 ) - (9 x pi x X 2 ) = 7piX 2 Therefore the required ratio = 7piX 2 / 3piX 2 = 7/3 Hence the answer is 7:3 Question 2 88 and 66 are ...

Below are three problems on linear equations. You have to form the equations by using the given information. Question 1 A railway half ticket( for kids below 5 years) costs Rs. 150 and full ticket(for above 5 years) costs Rs. 250. The daily report says that for a particular day, 5000 passengers have travelled and the total collection is Rs.10,50,000. How many kids(below 5 years) have travelled on that day? a)1000 b)2000 c)2500 d)3500 Answer : b)2000 Solution: Let 's' be the number of kids travelled on that day and 'b' be the number of passengers(above 5 years) travelled on that day. Therefore, s + b = 5000 ... eqn (1) Each half ticket's cost is Rs.150 and Each full ticket's cost is Rs.250. Total collection of amount = 150s + 250b = 10,50,000 Or 150s + 250b = 10,50,000 ... eqn (2) Multiplying equation (1) by 150, we get 150s + 150b = 7,50,000 ... eqn (3) Subtracting eqn (3) from eqn (2), we get 100b = 3,00,000 Or b = 3000 We know that s + b =...

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 :...
