00 - GENUINE APTITUDE? |

Today's school methods are rote etc. developing tunnel vision - none of which
is desirable. The same school methods (along with GENUINE & ARTIFICIALLY CREATED
FORMULAE!) are dished out with great slogans and promises as aptitude development stuff.

Mugging up formulae and methods, drilling a 1000 times and vomiting answers at supersonic speeds is**not aptitude development!**

**Aptitude** is thinking and reasoning out of the box and not by rote memory
nor uni-directional thinking nor traditional thinking.

__A Sample Problem!__

A shirt costs Rs.840. There is a festival discount of
12
% on it. How much is the discount?
__School Solution__

1)
= **... ... ...** = Rs.105. (Using 'school definition' of percentage!).
This method needs working on paper and time.

__APTITUDE SOLUTIONS__

The solutions below are non-school, non-conventional & lateral
- true aptitude development material.

2) Of 840, 10% is 84; 2% is a fourth of 84, i.e. 21; so discount (total) is Rs.105.

3) 100% >> 50% >> 25% >> 12%; So halve 840 three times; 840 >> 420 >> 210 >> 105; so Rs.105.

4) 12% of 840 is simply 'one-eighth' of 840; divide 840 by 8; so is Rs.105.

These are mental calculations done in a couple of seconds - once your mind is trained, of course.

Remember we need to calculate 12
%. That is all.
