At a class party, Leah had a bag of sweets.
If each pupil receives 10 sweets, Leah is left with 34 sweets.
If each pupil receives 12 sweets, Leah is short of 48 sweets.
(a) How many pupils are there in the class?
(b) How many sweets does Leah have?

Answer: B. 41 pupils, 444 sweets

Let P be the number of pupils.
Equation: 10 * P + 34 = 12 * P - 48.
Move the numbers: 34 + 48 = 12 * P - 10 * P.
Solve: 82 = 2 * P.
Pupils = 82 / 2 = 41.
Sweets = (10 * 41) + 34 = 444.
Final Answer: (a) 41 pupils and (b) 444 sweets.
