Tip­ping the Scales

free brain teasers for frontal lobes

Ques­tion:
The top two scales in the image at the right are in per­fect bal­ance. How many dia­monds will be need­ed to bal­ance the bot­tom set?

This puz­zle helps you work out your exec­u­tive func­tions –sup­port­ed in the frontal lobes— by using your pat­tern recog­ni­tion, hypoth­e­sis test­ing, and log­ic.


ANSWER:

Four dia­monds

SOLUTION:

First add up the num­ber of clubs in the first two scales (5). Then count how many clubs are in the bot­tom scale (5). The do the same with the spades, which gets you 5 and 5. There are 4 dia­monds in the top two bal­anced scales. There­fore, it must take 4 dia­monds to bal­ance the third scale since all the oth­er mea­sure­ments are the same.

Archimedes made a plen­i­tude of sig­nif­i­cant sci­en­tif­ic dis­cov­er­ies through­out his life. He designed machines capa­ble of lift­ing attack­ing ships out of the water as well as mir­ror arrays capa­ble of focus­ing sun rays and set­ting ene­my ships on fire. He explained why and how bod­ies float in the water, help­ing the king ver­i­fy that his crown is indeed made out of pure gold.
