Q1.
Total age now > 10+7=17
(4117)/2 = 12 ...(both grow older by the same number of years)
Their total age will be 41 years in 12 years' time.
Q2.
Mass of (6540)= 25 sweets > 3200g  2125g = 1075g
mass of 1 sweet > 43g
Mass of basket > 2125g  40 x 43g = 405g
cheers.

Hi
You may use "Listing"
Total number of students for A, C,D and E  77
Find multiples of 5 and 7 after 77
Multiples of 5  80,85,90,95
Multiples of 5 + 1  81,86,91,96
Multiples of 7  84, 91
Multiples of 7 + 5  89, 96
The common number is 96
Least number of students in B  9677  19
Hope this helps
Best wishes
Very clear! Thanks a lot!

Assume all boys donated, total amount > 40 x $3 = $120
$120  $30 = $90  excess amount to be reduced by girls' donation
Number of girls = $90/($3+$2) = 18
Number of boys = 4018 = 22
cheers.

Luke had $140 and Issac had $92 at first. After they spent an equal amount of money, Luke had 4 times as much money as Isaac. How much did each of them spend?
(not sure if this has been asked before, pls refer me to correct page. Thanks!)

3 units > $140  $92 = $48
1 unit > $48 / 3 = $16
$92  $16 = $76
Each of them spent $76

Re: Q&A  P5 Math
Serene, Fabian and Eileen shared their prize money of $4100 among themselves. Twice of Serene's share was equal to 5 times of Fabian's share. 4 times of Serene's share was also equal to 3 times of Eileen's share. Calculate Serene's share.
Help ...... please. How should the answers be presented and is this really a P5 appropriate question?
Thank you very much.
