Odd days in 1600 years = 0
Odd days in 400 years = 0
9 years = (2 leap years + 7 ordinary years) = (2 * 2 + 7 * 1) = 11 odd days 4 odd days.
Jan. Feb. March April May June July Aug.
(31 + 28 + 31 + 30 + 31 + 30 + 31 + 15) = 227 days

45. A thief is noticed by a policeman from a distance of 200 m. The thief starts running and the policeman chases him. The thief and the policeman run at the rate of 10 km and 11 km per hour respectively. What is the distance between them after 6 minutes ?
Answer: 100 meter
Explanation:find the relative speed of the thief and policeman = (11-10)km/hr = 1 km/hr
Distance covered in 6 minutes = (1/60)*6=1/10km => 100meters
So distance between them after 6 minutes = (200-100)=100 meters

46. An industrial loom weaves 0.128 metres of cloth every second. Approximately, how many seconds will it take for the loom to weave 25 metre of cloth ?
Answer: 195 seconds
Explanation:Lets assume the time required to weave 25 meters = x sec.
Rule: More cloth means More time (Direct Proportion)
=> 0.128:1::25:x
=>x=[(25*1)/0.128]
=>x=195.31
So time needed ~195 seconds

47. There are three numbers, these are co-prime to each other are such that the product of the first two is 551 and that of the last two is 1073. What will be the sum of three numbers :
Answer: 85
Explanation:Given that numbers are co primes,
and two products have the middle number in common.
=> Middle number = H.C.F. of 551 and 1073 = 29
so first number is = 551/29 = 19
=> Third number = 1073/29 = 37
Therefore, sum of these numbers is = (19 + 29 + 37) = 85

48. When a student weighing 45 kgs left a class, the average weight of the remaining 59 students increased by 200g. What is the average weight of the remaining 59 students
Answer: 57
Explanation:Lets assume average weight of the 59 students = x kgs.
=> Total weight of the 59 = 59*x
Given when the weight of this student who left is added, the total weight of the class = (59x + 45)
The average weight decreases by 0.2 kgs, when these students included.
=> (59x+45)/60=(x-0.2)
=> (59x+45)= 60(x-0.2)
=> 59x + 45 = (60A - 12)
=> 45 + 12 = 60x - 59x
=> x = 57
