2 examples of P6 Maths problem sums :

1. David had 2 bags of marbles. After he had sold 44 marbles from Bag X to his friend, the number of marbles in Bag Y was 5/7 of the number of marbles in Bag X. Given that there were 2/5 as many marbles in Bag Y as in Bag X originally, find the number of marbles in Bag X at first.


2. John read a book in 3 days. He read 35% of the total number of pages in the book on the 2nd day. The ratio of the total number of pages of book he read on the 1st and 2nd day to the number of pages he read on the 3rd day was 11:9. If he had read 75 more pages on the 3rd day than on the 1st day, how many pages of the book did he read on the 2nd day ?


Not only must the child be good at Maths, he/she must also be good at English, in terms of interpreting and understanding the question. 🙂

Pls help. TIA.


Charlie had 148 pieces of $2 and $5 notes. She spent 60% of her $5 notes to buy a bag and then her mother gave her another six $2 notes. As a result, the number of $2 notes was thrice as many as the number of $5 notes left. Find the amount of money Charlie had left.
Let the number of 40% leftover $5 notes be 4u,
Then originally he would had 10u of $5 notes.

Since $2 notes is 3 times of leftover $5 notes, then the number of $2 notes is 12u. (From 4u x 3)

Including the six $2 notes his mother gave, the total number of notes he had before buying the bag is 154
10u + 12u = 154
22u = 154
u = 7

Number of $5 notes left = 4u =28
Value of $5 notes = 28 x 5 = $140

Number of $2 notes left = 12u = 84
Value of $2 notes = 84 x 2 = $168

Total value = $140 + $$168 = $308 ###

Answer: $308.
Solution:

Let T and F be the initial numbers of $2 and $5 notes. We have

(1) T + F = 148.

After buying the bag, the number of $5 notes she has is 0.4 F.
After her receiving another six $2 notes, the number of $5 notes she has is T + 6.
We are told that she then has thrice as many $2 notes as $5 notes.

Thus,

(2) 3 × 0.4 F = T + 6.

From (1), we have T = 148 - F. Plug this into (2) to get

3 × 0.4 F = 148 - F + 6.

Rearranging, we have 2.2 F = 154, and thus F = 70.

So T = 78.

And so the money she has at the end of the day is

0.4 F × 5 + (T + 6) × 2 = 0.4 × 70 × 5 + (78 + 6) × 2 = 140 + 168 = $308.

Hope this helps and feel free to ask for any clarifications.

SOS mum:
Hi, pls help. Many tks and God Bless:)


Harry paid $320 for 5 shirts and 2 pairs of pants. If he bought another shirt, he would have $15 left. If he bought another pair of pants, he would be short of $5. How much did Harry have?
Each pair of pants costs $20 more than each shirt.
If you Make shirt -> 1u, then pants -> 1u + 20

5u + ( 2u+ 40) -> 320
7u->280
U->40

He has : 320 + 40 + 15 -> $375

one extra shirt would leave him with $15 excess
1Extra pants will leave him wit $5 shortage
So a pant costs $20 more than a shirt

cost of 5 shirts + 2 pants = cost of 5 shirts + 2 shirts +2x$20
= 7 shirts+$40

7 shirts+$40 = $320
1 shirt = $40
He has $320+$40 ( cost of extra shirt) + $15 ( his excess) = $375

doraemo:
hi, another one.


please help.

After hiking for 30km, Martin took break before he continued hiking 1/3 of the remaining distance. He then realised that he still had ¼ of the total distance not completed. If Martin’s average speed was 6 km/h , how much time did he take to complete the entire hike?
Hope my solution is correct:

Total Distance -> 30 + u + u + u = 30 + 3u (deduce from first sentence)

u + u -> 1/4 of Total Distance (deduce from second sentence)
Total Distance -> 4 x 2u = 8u

So,

30 + 3u -> 8u

5u -> 30

1 u -> 6

Total distance -> 8 x 6 = 48

Time taken -> 48/6 = 8 hours
