Question

Pierre, Kelsey and Titus shared some magnets.

Pierre took 6 more than 1/4 of the magnets.

Kelsey took 2 more than 2/3 of the rest of the magnets.

Titus took the last 12 magnets. How many magnets did Kelsey take?

Answer

12 + 2 = 14
14 x 3 = 42 (rest of the magnets)
2 + (2/3) x 42 = 30

Ans : 30 magnets.

Start from the back, where there are 3 units, and Kelsey took 2u + 2. That means the remainder will be 1u – 2, which Titus took.
1u- 2 = 12
u = 14.

Kelsey took 2u + 2 = 30 magnets #

 

For practice try to work out how many Pierre took. (22)
