Pls assist

1) Last year, the ratio of the number of female members to the number of male members in a club was 8 : 5.
This year, 48 female members joined the club.
As a result, the ratio became 8 : 3. How many members were there in the club last year?

and each girl receives \$4. Given that the ratio of adults to boys to girls is 3 : 4 :2, how many more boys than girls are there?

Thanks

Q1
Since the males remained the same, change units for male to the same number.

Last year,
8 x 5 : 3 x 5
40 : 15

This year,
8 x 3 : 5 x 3
24 : 15

Difference in female, will be
(40 - 24)units ----------> 48
16 units -----------------> 48
1 unit --------------------> 48 รท 16 = 3
Last year ---------------> (24 + 15)units x 3 = 117members

Q2
I believe the amount each adult gets is missing. Need that info to solve.
