Based on the logic of the first four pairs of words and shapes, figure out what the fifth word is.

The third letter is N if the number of shapes is 2 and R if the number of shapes is 3.

The fourth letter is T if the shapes are arranged vertically and S if the shapes are arranged horizontally.

Birthday Twins

Section: Brain Teasers Category: Insight
Difficulty:

Darma and Greg are twins, Greg being the older one by just few moments. However, several times in their lives, Darma celebrated her Birthday two days before Greg did. How is this possible?

Darma and Greg were being delivered on a plane/ship which was passing the 180th meridian. This way Greg got born on 1st of March and Darma got born on 28th of February. Therefore, during leap years, Darma will celebrate her Birthday 2 days before Greg.

Tough Decisions

Section: Brain Teasers Category: Insight
Difficulty:

You are driving your car along the road in a very harsh snowy weather and reach a bus stop. On this bus stop you see that there are three people waiting – your best friend, a sick old lady and the girl of your dreams. The car unfortunately can accommodate only 2 people (including you), so you can not take all of them with you. What will be your choice?

The best solution is to let your friend drive the old lady and you stay with the girl of your dreams on the bus stop.
