Video solution here (3:26):
Key Habit for Speed on Data Sufficiency:
We often don't need to actually solve.
[b]We just need to know that we CAN answer the question.
This can save a lot of time on problems with harder calculations.
With 2 UNIQUE LINEAR equations and 2 unknowns (or 1 equation & 1 unknown, 3 equations and 3 unknowns, etc.), we can solve.
Caveats:
⚠️Watch out when it's asking for a "Combo" of two variables. For example, if the question asks for the ratio "X/Y", we can solve with the one equation 2x = 3y. We get "two birds with one stone."
⚠️The equations must be UNIQUE. A common trap is where one equation is just a multiple of the other. For example, x + 2y = 3 and 3x + 6y = 9 are really just the same equation!
⚠️Quadratics often have 2 different solutions for 1 equation. For example, \(x^2 = 9\) has 2 different solutions: x=3 OR x=-3.

My two cents, since we know the post discount price for adults and children (4950 & 4320) respecfully.
S1: Tells us that there were 6 adults (29700/4950) = 6 --- children could be >=4 since the question tells us there were at least 10 people - (I)
S2: Tells us that children's total tickets price was 4860 more than adullts - Not enough info (I)
S1+S2 : Take S2's 4860 and add it to S1's 29700, you get 34560 and divide by the children's post discount price (34560/4320) = 8 children
Hope it's the right way to think
