Newbies here, with ratio problem to solve, which goes this way as below:


The ratio of the number of daisies to the number of orchids in Basket A and Basket B are 2:1 and 2:7 respectively. Basket A has 2/3 times as many flowers as Basket B.

(a) Find the ratio of the number of daisies in Basket B to the number of daisies in Basket A.

(b) When 18 orchids are moved from Basket B to Basket A, the ratio of the number of daisies to the number of orchids in Basket A becomes 8:7. How many orchids are there in Basket A now?

Thanks.

:shock:

Sorry Herbie,

Vc = speed of train towards Town C

Ratio of total no. of flowers in Basket A : Basket B = 2 : 3

Basket B :
Daisies : 2u
Orchids : 7u
Total : 9u

Basket A (Total = 2/3 x 9u = 6u)
Daisies : 4u
Orchids : 2u

(a)\tRatio = 2: 4 = 1 : 2
(b)\tBasket B (Orchids) : 7u - 18
Basket A (Orchids) = 2u + 18

\tNew ratio of daisies to orchids in Basket A = 8 : 7
\t4u/(2u + 18 ) = 8/7
28u = 16u + 144
12u = 144
1u = 12

No. of orchids in Basket A now= 2u + 18 = 24 + 18 = 42

Take Anne's hairclip as 100%. Mina's hairclips will be 80%. Caili is 20% more than Mina - so it is 80% + 16% = 96%

Thus Caili's hairclips as a percentage if Anne's is 96%

Hi


Pls help with this question.Thanks

Gibson had 50-dollar, 20-dollar and 10-dollar tickets for a school funfair in the ratio 1:5:4.
The total value of the funfair tickets was $3420.
a) Find the no. of each type of tickets he had.
b) After selling 1/4 of the 10-dollar tickets and a few 20-dollar tickets, he found that 2/11 of the remaining tickets were 50-dollar tickets.
How many 20-dollar tickets did he sell?

At first: M has 10U + 200, E has 10U
Step 1 - M give E 60%: M has 4U + 80, E has 16U + 120
Step 2 - E give M 25%: M has 8U + 110, E has 12U + 90

12U + 90 - 200 = 8U + 110
4U = 310 - 90 = 220
U = 55

Initially Marina has 550 + 200 = 750 books
