Total price of all notepads = $40.05

Integer multiple of 40.05 are

3 x 13.35 = 40.05

5 X 8.01 = 40.05

Yellow light flashes 6 times per minute i.e. after every 10 seconds.

Blue light flashes 4 times per minute i.e. after every 15 seconds.

Red light flashes 30 times per minute i.e. after every 2 seconds.

LCM of 10,15 & 2 is 30.

So, all lights flash simultaneously after 30 seconds.
