Hi,

Please help with the following another P3 question. Thanks!

Mrs Singh has a certain number of sweets to distribute to her class. If she gives each of them 5 sweets, she will have 54 extra sweets. If she gives each of them 8 sweets, she would need another 33 more. How many children does she have in her class?

Hi kwcllf,

Thks for your assistance. But the answer is 29 children...quite puzzle.

Hi Violet04,

Sorry. I read the question wrongly that Mrs Singh has extra 33 sweets. If she is short of 33 sweets instead, the correct answer is 29 children.

54 + 33 = 87 sweets

Difference between 5 & 8 sweets = 3 sweets

Therefore, No. of children = 87/3 = 29 children.

Hi Violet04,

MathIzzzFun has been superbly helpful and he has helped many of us solved many problem sums. You can always post your questions here and most likely he will assist.

I am very blur also at first. But you can go Popular Bookstore to get this book called CHALLENGING MATHS PROBLEMS MADE EASY. THE book can help you with the basics of solving such questions and it is how I managed to learn how to teach my kids solve some of their maths problems. Perhaps you may want to take a look at the book.

Mary was preparing some lemon syrup concentration for her friends. The amount of lemon syrup initially used was 3/7 the amount of water used. To make it more diluted, she decided to add 1100 ml more water into the syrup drink such that 1/5 of the concentration was syrup. How much syrup did she use?


Thank you.

Thank you.

Hi
key --> amount of syrup remained the same

At first --> Lemon syrup : Water = 3u : 7u
In the end --> Lemon syrup : Water = 1: 4 = 3u : 12 u

12u - 7u --> 1100 ml , 1u --> 220 ml
Amount of Lemon syrup --> 3u --> 3 x 220 ml = 660 ml

cheers.
