Quicker Maths by M Tyra

Today, let me confess something to all of you. I am sure this will help all the readers.

So here I go. This is regarding the name of the website - QuickerMaths.com. It is inspired by the name of the best mathematics books I have ever come across. This book helped me a lot in clearing CAT and reaching to IIM. The inspiration of creating an interactive platform (QuickerMaths.com) came from this book. As a token of appreciation and to do my bit today I will tell you about this book named -

Magical Book on Quicker Maths

Author: M. Tyra

About the book: The book will be a boon for the aspirants of today’s competitive exams irrespective of their background – whether they come from arts, science or commerce stream. Concepts have been clarified so well, that even if one is vaguely familiar with them as in the case of non-mathematics students, understanding will not be a problem. Direct formulae are beneficial for one and all. They save time and time is precious for everyone.

Must for Competitive Preparation

The book is profusely illustrated. Avoiding the temptation for haste and ending up with a cookbook, the author has put in two years of intensive effort and research. Ideas have been taken from available study material, number theory, readers’ suggestions and, finally Vedic mathematics.

Recently I purchased the latest edition of this book from online book store Flipkart.com

Rules:

The link might be a blogroll link like the one in the image below on fireup blog

The Cycle Race Brain Teaser

Krishna and Bala decided to have a bicycle race. But the problem was that they had only one bicycle between them! Krishna had a solution. As the road to the airport had a stone demarcating every kilometer, he would ride from the first stone to the fifth, and Bala could ride the remaining distance from the fifth to the tenth stone. Then they could take their respective times with a stopwatch to see who was faster. The ‘race’, however, was a failure. Can you say why?

Solve a Dilemma

What is wrong with this proof?

2 = 1

a = b

a² = ab

a² – b² = ab – b²

(a + b) (a – b) = b (a – b)

a + b = b

2b = b

2 = 1

A Puzzle Of Cultural Groups

My club has five cultural groups. They are literary, dramatic, musical, dancing and painting groups. The literary group meets every other day, the dramatic every third day, the musical every fourth day, the dancing every fifth day and the painting every sixth day. The five groups met, for the first time on the New Year’s day of 1975 and starting from that day they met regularly according to schedule.

Now, can you tell how many times did all the five meet on one and the same day in the first quarter? Of course the New Year’s day is excluded.

One more question-were there any days when none of the groups met in the first quarter and if so how many were there?

Vedic Multiplication by 9, 99, 999 and so on

When any number has to be multiplied by a series of 9s, like 9, 99, 999, 9999 and so on than we can apply this very simple vedic maths technique to increase your speed of calculation.

Multiplication with 9/ 99 / 999 and so on.

we know, 789 × 999 = 788,211

You will get the answers in two parts,

The left hand side of the answer: subtract 1 from 789, which is 788
The right hand side of the answer subtract 789 from 1000 = 1000-789= 211

Thus, 999 x 789 = 789-1 | 1000-789 = 788, 211 (answer)

{for the right hand side of the answer, 789 should be subtracted from (999+1)}

or, 99999 x 78 = 78-1 | 100000 - 78

= 7799922

{78 should be subtracted from (99999+1)}

Another example:

1203579 × 9999999 = 1203579-1 | 10000000- 1203579

=120357887964 21

Number in red is 1 less than 1203579. Number in blue is (10000000-1203579). Hence the answer.

This method has to be altered a little bit when number of 9s are lessers than the number of digit in the divisor.

1432 x 9 = 1432 (10 – 1) = 14320 – 1432 = 12888

So for multiplication with 9, put a zero after that number and subtract the number itself from that.

Likewise for 99 put two zeroes after that number .

3256 x 99 = 325600 – 3256 = 322344

Clock Puzzle

Sitting uncomfortably in the doctorâ€™s waiting room one day, I stared at the clock on the wall. I had been waiting for what seemed to be a very long time.

To take my mind off the reason for the visit I started to invent little puzzles to solve.

Estimating the length of the minute hand of the clock to be 4 inches, I calculated the distance the hand had travelled around the clock since I arrived to be 15 inches.

How long had I been waiting?
