“God used beautiful mathematics in creating the world.” —Paul Dirac

{Coach Alice’s Note: LETer (or LET taker), are afraid of Math? Do you feel like skipping test items when you see that they deal with Math problems? Are you ready to love Math?

It’s time for a mindset change if you are aiming to top or pass the LET.

Think about Math as a subject that you face everyday from the time you were conceived, your growing years, times at school, starting a family until you retire.

Here are some sample LET test items for Math, as shared by occasional MindGym LET Math coach Gail Beltran.}

Ratio

  1. The ratio of blue to red marbles is 16 to 9. If there are 96 blue marbles in the box then how many of the following is in the box?
  2. A total of 450 is divided into equal shares. If Joshue receives 4 shares, Barbie receives 3 shares and Jake receives the remaining two shares, how much money did Jake receive?
  3. A 6 ft tall tent standing next to a cardboard box casts a 9 ft shadow. If the cardboard box casts a shadow that is 6 ft long then how tall is it?
