Answer : -
My work:
Number of sweets Tom have = T
Number of sweets Nora have = N
Number of sweets = S
[1] We know Tom and Nora shared some sweets. T + N = S
[2] Nora received 3/5 of the sweets. She gave Tom 8 sweets so that both of them had an equal number of sweets. 3/5N - 8 = 2/5T + 8
Now here is my question, did I do it mathematically correct?
From [2], I changed the N and the T to an S
so 3/5S - 8 = 2/5S + 8
so, S = 80.
Answer : -
Only need 1 variable: t = total sweets
3t/5 - 8 = 2t/5 + 8 ; multiply by 5:
3t - 40 = 2t + 40
t = 80
Answer : -
As Nora started with 60% of the sweets, she gave away 10%, and so there were 80 sweets.

Answer:
- Nora received 3/5 of the sweets means Tom received 2/5
- if Nora gives tom 8 sweets and they both got now equal portions means they both have 2.5/5
- Nora had 3/5 then she gave 8 sweets to Tom and now she is left with 2.5/5 means 0.5/5 is equal to 8 sweets
- 0.5 = 8 sweets
- 0.5x10=5
- 8x10=80 sweets
- all 5 portion are equal to 80 sweets
