Explanation:
The total number of notebooks sold on Monday
= > 420 + 260 = 680
The total number of notebooks sold on Friday
= > 360 + 400 = 760
Required difference = 760 – 680 = 80

Explanation:
Total number of notebooks sold on Tuesday
= > 480 + 320 = 800
Total number of notebooks sold on Wednesday
= > 540 + 380 = 920
Total number of notebooks sold on Saturday
= > 920 * (140/100) = 1288
Required % = (800/1288) * 100 = 62.11% = 62 %

Explanation:
The average number of plain notebooks sold on all the
given days together
= > (420 + 480 + 540 + 600 + 360)/5 = 480
The average number of ruled notebooks sold on all the
given days together
= > (260 + 320 + 380 + 440 + 400)/5 = 360
Required difference = 480 – 360 = 120

Explanation
The total number of plain notebooks sold on Monday,
Wednesday and Friday together
= > 420 + 540 + 360 = 1320
The total number of ruled notebooks sold on Tuesday,
Wednesday and Thursday together
= > 320 + 380 + 440 = 1140
Required ratio = 1320 : 1140 = 22 : 19

Explanation:
The total number of notebooks sold on Thursday
= > 600 + 440 = 1040
The total number of non defective notebooks sold on
Thursday
= > 1040 * (5/8) = 650

Profit on A = 12%
Overall profit = 15%
Profit on B = (15 * 2) - 12 = 18%
=> 90/18 * 100 = 500
CP of A = 500
M1 * W1 = M2 * W2
40 * 48 = 64 * x + 96 * 16(2/3)
1920 = 64x + 1600
x = 5

M1 * W1 = M2 * W2
40 * 48 = 64 * x + 96 * 16(2/3)
1920 = 64x + 1600
x = 5

In initial mixture,
Water = 24%
Milk = 76%
In 50 liter,
Water = 50/100 * 24 = 12
Milk = 50/100 * 76 = 38
Remaining milk = 76/76 * 100 = 100
Initial milk = 100 + 38 = 138 lit

The ratio of speed of boat and current = 10 :1
Downstream speed = 10 + 1 = 11
Upstream speed = 10 -1 = 9
Downstream speed : Upstream speed = 11 : 9
Time ratio = 9: 11
The ratio of time taken to travel the distance “D " in
downstream and D - 45
= 3 : 2
Let
Time to travel D = 9 (from above ratio)
Time to travel D – 45 = 9/3 * 2 = 6h
Then the Distance D = 45/(9 - 6) * 9 = 135 km
