Linda owned 4/5 as many comics as the total collection owned by fazillah and Winnie. If Winnie owned 169 fewer comics then Linda, how many comics must Fazillah and Linda each give to Winnie in order for the three :? gilrs to have same number of comics?

Hi

Fazillah : Linda + Winnie --> 2 : 3
Fazillah : Linda + Winnie + Fazillah (=Total) --> 2 : 5

Linda : Winnie + Fazillah --> 4 : 5
Linda : Linda + Winnie + Fazillah (=Total)--> 4 : 9

Equalize Total -
Fazillah : Total --> 18u : 45u
Linda : Total --> 20u : 45u
So, Winnie --> 45u - 18u - 20 u = 7u

Linda had 169 more comics than Winnie
So, 20u - 7u --> 169
13u --> 169, 1u --> 13 comics

Total --> 45u, 45u / 3 = 15u --> each girl will have 15u in the end.
Number of comics given by Fazillah to Winnie --> 18u - 15u = 3u --> 39 comics
Number of comics given by Linda to Winnie --> 20u - 15u = 5u --> 65 comics

cheers.

Hi

Age difference will always remain the same.

Age difference = 80 - 52 = 28
When grandma was 3 times as old as her son,
grandma's age --> 3u
son's age --> 1u
age difference --> 2u
2u --> 28, 1u --> 14
52-14 = 38 years ago

cheers.

1) Dan harvested some apples. He sold to Adam 3/4 of the apples and another 105 apples. He sold to Geradine 3/4 of the remainder but took back 55 apples. Dan had 890 apples left.


a) How many apples did Geradine have after returning 55 apples to Dan
b) How many apples did Farmer Dan harvest?

2) Tank X and Y are each filled with some water. If water from tank Y is poured into Tank X until water in tank X reaches the brim, there will be 8L of water left in Tank Y, If water from Tank X is poured into Tank Y until water in Tank Y reach the brim, there will be 26L of water leftt in Tank X. The ratio of volume of of Tank X to Taank Y is 5 : 3. How many more litres of water are needed to fill both tanks to their brim?

3)A florist had total 272 roses and lilies in ratio of 12:5. After selling away twice as many roses as Lilies, the ratio of roses to Lilies was 5:2. How many roses did she shell?

Hi

Q1. You should be able to solve this... I will provide some pointers...
Before Geraldine returned the apples to Dan, how many did Dan have ? This number represent 1/4 of the remainder after selling Geraldine the apples. You can work backwards from here.

Q2.

Q3.
At first,
Roses --> 12/17 x 272 = 192
Lilies --> 272 - 192 = 80

Roses left : Lilies left
= 192-2u : 80 - 1u
= 5 : 2

cross multiply or equalize:
384 - 4u = 400 - 5u
1u = 16

Roses sold --> 2 x 16 = 32

cheers.
