Level 2 PSLE Dots are placed at an equal distance from each other along the 6 sides of shape A. The number of dots on each side is the same and each corner has a dot on it. When there are 24 dots on shape A, there are 5 dots on each side.
When there are 90 dots on shape A, how many dots are there on each side?

Level 3 PSLE
Victoria hung some identical oval rings vertically. The thickness of each oval ring was 1 cm. The figure shows how the oval rings are connected.
What was the distance from the top of the 1st oval ring to the bottom of the 3rd oval ring?
The distance from the top of the 1st ring to the bottom of the last ring was 177 cm. How many oval rings did Victoria hang altogether?
