Question: this question is used to see the mental and logical thinking of humans.

A bat and a ball together cost one $1.10.  If the bat cost $1 more than the ball, what is the price of each? [First work out in ten seconds; then take your time to work out the answer and see which one is correct.]

Solution

Bat and ball together cost = $1.10

The bat, as you already know, costs $1 more than the ball.

Now using the information above you can find their costs using algebraic equations. 

Let’s denote the ball as x and bat as y and carry out the equations.

x + y = $1.10

Or x + ($1 + x) = $1.10

Or 2x + $1 = $1.10

Or 2x = $1.10 - $1

Or 2x = $0.10

Or x = $0.05

Therefore, the ball costs $0.05 and the bat costs $1.05.

Do some Snakes wear Glasses?

Sham S. Misri

Snakes are scaly, cold blooded reptiles without limbs. Most of the biggest snakes are pythons-powerful, non venomous reptiles that kill their prey by coiling around it and squeezing until it cannot breathe.

Three fifths of all snake species belong to the colubrid family. Most are harmless, but some have venomous fangs at the backs of their mouths. Snakes shed their outer skin at least once a year, emerging with glossy scales and brighter colours.

The statement- Do some snakes wear glasses?

Of course they do not, but the Indian cobra has sometimes been described as wearing glasses. This is because when it rears up, its head is covered with a sort of hood on which there is a pattern that looks like a pair of glasses.

Cobras are among the deadliest of venomous snakes. They are armed with a nerve poison that paralyzes their victims so they cannot breathe and they die from suffocation. Thus a single cobra bite can be fatal. The black necked variety is common in Africa. This particular variety can shoot its venom as far as two meters into the eyes of an opponent. The venom or poison is powerful enough to blind an enemy temporarily or permanently.

Coral snakes, which live in South America, are also members of the cobra family. They are extremely poisonous. These snakes have a very distinctive appearance. Their shiny skin is coloured by alternating bands of black, yellow and red. Like many animals, coral snakes will not attack unless they are disturbed in some way.
