George and Mark can paint 720 boxes in 20 days, Mark and Harry in 24 days and Harry and George in 15 days. George works for 4 days, Mark for 8 days and Harry for 8 days. The total number of boxes painted by them is
A252
B516
C348
D492
Answer: Option C
Explanation:Capacities of these people as followes
G + M = 720/20 = 36
M + H = 720/24 = 30
H + G = 720/15 = 48
Adding all above we get 2(G + M + H ) = 114 => G + M + H = 114/2 = 57
Now individual capacities are given below
G = 27 ; M = 9; H = 21
So 27 * 4 + 9 * 8 + 21 * 8 = 348

From 2001 to 2028 = 28 + 7 = 35 = 0 ( 35/7 remainder zero)
From 2019 January 1 to 7 = 7 = 0

Two decks of cards are there. Each deck contains 20 cards, with numbers from 1 to 20 written on them. A card is drawn of random from each deck, getting the numbers x and y What is the probability that log x + log y is a positive integer. Logs are taken to the base 10.
A3/200
B29/200
C29/200
D1/50
Answer: Option C
Explanation:Log x + log y = log(xy)
log xy is integer when (x,y) = (1, 10), (10, 1), (10, 10), (5, 20), (20, 5), (2, 5), (5, 2)
So required probability = 7/400

The remainder when m + n is divided by 12 is 8, and the remainder when m - n is divided by 12 is 6. If m > n, then what is the remainder when mn divided by 6?
A3
B4
C2
D1
Answer: Option B
Explanation:m+n+8 and m+n+6 is completely divisible by 12.
m+n=8 ----- (1)
m-n=6 ------(2)
By, solving these two equation we get, m=7 & n=1
mn = 7
so when we divide 7 by 6 , we get remainder 1.

George walks 36 kms partly at a speed of 4 kms per hour and partly at 3 km per hour If he had walked at a speed of 3km per hour when he had walked at 4 and 4 km per when he had walked at 3 he would have walked only 34 kms. The time (in hours) spent by George in walking was
A8
B12
C5
D10
Answer: Option D
Explanation:Let George walked "a" hours at 4 kmph, and "b" hours at 3 kmph.
Given, 4a + 3b = 36 - - - (1)
3a + 4b = 34 - - - (2)
Adding the above two equations and simplifying them, a + b = 10.

Of a set of 30 numbers, average of first 10 numbers = average of last 20 numbers. Then the sum of the last 20 numbers is?
A2 x sum of first ten numbers
B2 x sum of last ten numbers
Csum of first ten numbers
DCannot be determined.
Answer: Option A
Explanation:sum = average x number of observations.
Let the common average = x
Now sum of first 10 numbers = 10x
Sum of the last 20 numbers = 20x.
So sum of the last 20 numbers = 2 × sum of the first ten numbers.

Out of 9 person, 8 person spent RS.30 each for their meals. The 9th one spent Rs.20 more than the average expenditure of all the nine. The total money spent by all of them was:
ARs.260
BRs.290
CRs.292.50
DRs.400.50
Answer: Option C
Explanation:Let the 9th person spend Rs x.
Then the total sum spent by the nine people = 30 x 8 + x
= 240 + x.
So the average expenditure = (240 + x)/9.
Now x is 20 more than the average expenditure.
So, x = (240 + x)/9 + 20
Therefore x - 20 = (240 + x)/9
Thus, 9x - 180 = 240 + x
Or, 8x = 420
Or x = 52.50
Therefore total money spent = 240 + 52.50 = 292.50
