Solution:
Given:
Tonya has 50 stamps.
Ann has 5 less stamps than Tonya.
Pam has 12 fewer stamps than Ann.

To find the total number of stamps, we'll first determine the number of stamps Ann and Pam have.

Ann's stamps:
Since Ann has 5 fewer stamps than Tonya, Ann has 50 - 5 = 45 stamps.

Pam's stamps:
Pam has 12 fewer stamps than Ann, so Pam has 45 - 12 = 33 stamps.

Now, to find the total number of stamps, we'll add up the individual counts:

Total number of stamps = Tonya's stamps + Ann's stamps + Pam's stamps
= 50 + 45 + 33
= 128

Therefore, the three girls have a total of 128 stamps altogether.

To determine which side won and by how many runs, we need to calculate the total runs scored by each team in both innings and then compare the results.

West Indian Team:
Total runs scored = 304 (first innings) + 265 (second innings) = 569 runs

East Team:
Total runs scored = 328 (first innings) + 225 (second innings) = 553 runs

Now, we can find the winning team and the winning margin:
- The West Indian Team scored 569 runs in total.
- The East Team scored 553 runs in total.

Therefore, the West Indian Team won the cricket match by (569 - 553) 16 runs.
