Write down your correct answer and show your workings:

  1)  There are 34 006 animals on a farm.   18 408 were chickens.
       The rest were ducks and geese. 
       If there were 9 923 geese, how many more geese than ducks were there?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

  2)  Shafil is 34 years younger than his father. 
       6 years ago, his father was 3 times as old as he was.
       How old is Shafil's father now?
 
 
 
 
 
 
 
 
 
 
 
 
 
 

  3)  Shaun had three times as much money as Raju.
       Soo Hui had eight times as much as Shaun.
       If Raju and Shaun had $272 altogther, how much money did Soo Hui have?
 
 
 
 
 
 
 
 
 
 
 
 
 
 

  4)  Box A contained 623 egg tarts.
       It contains 258 more egg tarts than Box B.
       After some egg tarts were transferred from Box B to Box A, Box A contained thrice as many egg tarts as Box B.
       How many egg tarts were transferred from Box B to Box A?
 
 
 
 
 
 
 
 
 
 
 
 
 
 

  5)  Sam has a total of 25 twenty cent coins and fifty cent coins.
       They add up to $8.30.
       How many twenty cent coins and fifty cent coins does he have?
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

Answers:

  1) 34006 - 18408 = 15598 (Total - Chickens)
      15598 -  9923 = 5675    (Balance - Geese)
      9923 - 5675 = 4248       (Geese - Ducks)

      There are 4248 geese than ducks.

  2) 34 / 2 = 17 (Assume that both is of same age and divide by half)
      17 x 3 = 51 (Father is 3 times older)
      51 + 6 = 57 (Plus 6 years ago)

      Shafil's father is 57 years old. 

  3) Shaun   1    1   1
      Raju      1
      Shaun and Raju total = 4 units
      272 / 4 = 68

      8 x 3 = 24  (Shaun)
      Soo Hui (8 times of Shaun)
      Since Shaun has 3 units, Soo Hui will have 8 x 3 = 24 units
      68 x 24 = 1632

     Therefore, Soo Hui had $1632

  4) 623 - 258 = 365
      365 + 623 = 988 (Box A 3 times more than B)

      A    1   1   1
      B     1
      Total = 4 units

      988 / 4 = 247
      365 - 247 = 118

      118 egg tarts were transferred from Box B to Box A.

  5)  Assume 25 coins. 
       Start by divding into half and give the lower value the extra.
       13 ->  20 cent coins 
       12 ->  50 cent coins

       20 cent coins     Total of 20 cent coins    50 cent coins    Total of 50 cent coins    Total     Check
            13                    13 x 20 = $2.60                   12                 12 x 50 = $6           $8.60      Wrong
            14                    14 x 20 = $2.80                   11                 11 x 50 = $5.50       $8.30      Correct
