TCS Company Numerical Ability Permutation and Combination

the adjoining diagram we have a stair case in which each step has length x=5 width y=2 depth z=1 foot.smart ant wishes to go from a to b what is the short dist it can take?

Read Solution (Total 3)

Since the step forms a cuboid,the diagonal length would be √(a2+b2+c2).so the ans would be √(5^2+1^2+2^2)=5.47
Not sure abt ans

ant want to move extreme of the cuboid. first see the top surface.. shortest distance is always hypotenuse. now open the cuboid and make a new triangle by adding depth on lower side so that squaring don't make big difference i.e L=2+1 ,B=5. H(min)= 5.8

a thread and a cuboid or a folded paper will help u to imagine easily.

Girish Passage:
It is commonly assumed that dinosaurs went extinct 67 million years ago
when a cosmic bomb devastated this planet's surface and changed its
climate so drastically that it did not support dinosaur life any longer. Humans
appeared on the fossil record millions of years later To estab ish a link
between these two species does not seem possible. Could this assumption
be wrong?
In 1966, near the little town of Ica in the Peruvian mountains, the town
physician Dr Cabrera found thousands of stones etched with images and
many of them showed humans and dinosaurs living together. The mystery is
deepened by the fact that some stones at Ica show this planet's surface with
a distribution of the continents as it was approximately 13 million years ago
Moreover, Dr. Cabrera found human remains next to plant specimens as they
existed during the Mesozoic age, which ended with the demise of the
dinosaurs.
The only possible explanation can be that this planet is home to two worlds:
the present one and another one, which lags 13 million years behind in its
geologic evolution. This other world did not experience an extinction of the
dinosaurs and, therefore, evolution took an entirely different course.
Humans and dinosaurs did coexist in this parallel world.
Two parallel worlds for one planet is a fantastic concept It means when one
world disappears the other materializes. The change from one world to the
other must have a reason and we can only takes guesses what this reason is
