Hi,


Need help on the model for the following:

In a train, there were 1/2 as many adults as children. The number of boys was 24 more than the number of men. Given that there were 40 women and 88 girls, how many people were there in a train?

Thanks in advanced

Men --------[---------]
Boys -------[---------][----24----]
Women----[-----40-----]
Girls -------[------------88-----------]

Adults------ [---------][-----40-----]
Children----[---------][-----40-----][---------][-----40-----]
Children----[---------][----24----][------------88-----------]

Compare the models of Children
[-----40-----][---------][-----40-----] --> [----24----][------------88-----------]
40 + [---------] + 40 --> 24 +88
80 + [---------] --> 112
[---------] --> 32

Men --> 32
Boys --> 32+24 = 56

Total no of people --> 32 + 56 + 40 + 88 = 216

OR

Adults --> 32 + 40 = 72
Children --> 2*72 = 144

Total no of people --> 72 + 144 = 216

Thanks jieheng for the detail models

Thanks to BigDevil, Maths Tutor Mr. Lim and edlynnalexander for the working answer using Guess & Check and Assumption.


Though for assumption, I am still confuse. Step 1 assume all pupils are girls, can use boys?
Steps 3 is the total cards 1 boy and 1 girl have, correct?

Sorry as I am still learning assumption method, thanks

Hi,


Need advise on the following, other than using Assumption method, is there another method to use? Thanks in advanced

Q) There were 35 pupils in a class. Each boy had 5 cards and each girl had 8 cards. The boys had 6 more cards than the girls. How many boys were there in the class?

Hi edlynnalexander,


Thanks for the 2nd method of solving, though pardon me, how do you derive on the unit as 3unit for 4yo and 2 unit +2 for 5yo? :scratchhead:

Hi,

Will like to seek advise on what is the model to use for this question, assumption?

Q) Miss Carol gave her pupils 114 sweets on Children's Day. Each 4-year-old child received 2 sweets and each 5-year-old child received 3 sweets. The 5-year-old children received a total of 6 more sweets than the 4-year-old children. How many pupils does Miss Carol have?

Thanks in advance

Thanks in advance

four year old sweets [----]
five year old sweets [----][6]
total = [----]+[----]+6 = 114
[---]= 54
since each four year old has 2 sweets there are 54/2 = 27 four year old kids.
there are (54+6)/3 = 20 five year old kids.
there are 47 kids altogether.

Hi,


Need help on these question:

1) Chris and Diane have some carnival tickets. If Chris sells 10 tickets per day and Diane sells 5 tickets per day. Chris will have 40 tickets left when Diane has sold all her tickets. If Chris sells 5 tickets per day and Diane sells 10 tickets per day, Chris will have 70 tickets left when Diane has sold all her tickets.
a) How many tickets does Chris have?
b) If each ticket is sold for $20, how much money can be collected from the sale of all their tickets?

For (a), I am trying to use algebra, but could not figure out after having the days as \"x\"

10x+40=5x
5x+70=10x.....is this correct?

Thanks in advance

hope this helps..
