1)  

There were 13 as many male passengers as female passengers on board a train. After 50 male passengers alighted at Orchard Station and 50 female passengers alighted at Sommerset Station, there were 211 as many male passengers as female passengers on the train. How many female passengers were there on board the train at first

Answer: 270 


SOLUTION 1 :

Since the number of male and female passengers who alighted from the train is the same, there is a constant difference.

Before 

Male passengers →  1 unit→   1 x 9 = 9 units
Female passengers →  3 units→  3 x 9 = 27 units
Difference →  2 units→  2 x 9 =  18 units

  

After

Male passengers→ 2 units→   2 x 2 = 4 units
Female passengers→ 11 units→  11 x 2 = 22 units
Difference9 units 9 x 2 = 18 units

 

Therefore,

Decrease in female passengers: 27 - 22 = 5 units

5 units → 50

1 unit → 50 ÷ 5

              = 10

27 units → 27 x 10

              = 270 female passengers at first



2)  

There were 13 as many male passengers as female passengers on board a train. After 18 male passengers alighted at Orchard Station and 18 female passengers alighted at Sommerset Station, there were 29 as many male passengers as female passengers on the train. How many female passengers were there on board the train at first

Answer: 126 


SOLUTION 1 :

Since the number of male and female passengers who alighted from the train is the same, there is a constant difference.

Before 

Male passengers →  1 unit→   1 x 7 = 7 units
Female passengers →  3 units→  3 x 7 = 21 units
Difference →  2 units→  2 x 7 =  14 units

  

After

Male passengers→ 2 units→   2 x 2 = 4 units
Female passengers→ 9 units→  9 x 2 = 18 units
Difference7 units 7 x 2 = 14 units

 

Therefore,

Decrease in female passengers: 21 - 18 = 3 units

3 units → 18

1 unit → 18 ÷ 3

              = 6

21 units → 21 x 6

              = 126 female passengers at first



3)  

There were 13 as many male passengers as female passengers on board a train.

After

Male passengers→ 2 units→   2 x 2 = 4 units
Female passengers→ 9 units→  9 x 2 = 18 units
Difference7 units 7 x 2 = 14 units

 

Therefore,

Decrease in female passengers: 21 - 18 = 3 units

3 units → 24

1 unit → 24 ÷ 3

              = 8

21 units → 21 x 8

              = 168 female passengers at first



4)  

There were 29 as many male passengers as female passengers on board a train. After 40 male passengers alighted at Orchard Station and 40 female passengers alighted at Sommerset Station, there were 17 as many male passengers as female passengers on the train. How many female passengers were there on board the train at first

Answer: 432

Male passengers →  2 units→   2 x 6 = 12 units
Female passengers →  9 units→  9 x 6 = 54 units
Difference →  7 units→  7 x 6 =  42 units

  

After

Male passengers→ 1 unit→   1 x 7 = 7 units
Female passengers→ 7 units→  7 x 7 = 49 units
Difference6 units 6 x 7 = 42 units

 

Therefore,

Decrease in female passengers: 54 - 49 = 5 units

5 units → 40

1 unit → 40 ÷ 5

              = 8

54 units → 54 x 8

              = 432 female passengers at first

Female passengers →  9 units→  9 x 7 = 63 units
Difference →  7 units→  7 x 7 =  49 units

  

After

Male passengers→ 1 unit→   1 x 7 = 7 units
Female passengers→ 8 units→  8 x 7 = 56 units
Difference7 units 7 x 7 = 49 units

 

Therefore,

Decrease in female passengers: 63 - 56 = 7 units

7 units → 56

1 unit → 56 ÷ 7

              = 8

63 units → 63 x 8

              = 504 female passengers at first

After

Male passengers→ 2 units→   2 x 1 = 2 units
Female passengers→ 11 units→  11 x 1 = 11 units
Difference9 units 9 x 1 = 9 units

 

Therefore,

Decrease in female passengers: 18 - 11 = 7 units

7 units → 63

1 unit → 63 ÷ 7

              = 9

18 units → 18 x 9

              = 162 female passengers at first

Male passengers →  1 unit→   1 x 7 = 7 units
Female passengers →  2 units→  2 x 7 = 14 units
Difference →  1 units→  1 x 7 =  7 units

  

After

Male passengers→ 2 units→   2 x 1 = 2 units
Female passengers→ 9 units→  9 x 1 = 9 units
