Let's assume there are 'x' pupils in Mrs Lim's class.
If she gives each pupil 3 stickers, she will have 18 stickers left.
This means she originally had 3*x + 18 stickers.
If she gives each pupil 5 stickers, she will need another 30 stickers.
This means she originally had 5*x - 30 stickers.
Therefore, 3*x + 18 = 5*x - 30.
Subtracting 3*x from both sides, we get 18 = 2*x - 30.
Adding 30 to both sides, we get 48 = 2*x.
Dividing both sides by 2, we get x = 48/2.
Hence, there are x = <<48/2=24>>24 pupils in Mrs Lim's class. Answer: \boxed{24}.
