On BBC Leslie gave her a complex problem to solve. Shakuntala Devi provided the solution to the problem, yet Leslie claimed that the answer was incorrect until later he realized that the original answer was wrong. Shakuntala Devi was invited to various educational institutions in the Southern Methodist University, Dallas she was once asked to find the solution of, the 23rd root of a digit number. She obtained the result in 50 seconds whereas a Univac computer took more than a minute to solve it.

Shakuntala Devi even wrote books on mathematics for children. She was also popular as an astrologer with her strong mathematical knowledge. It became the first inclusive study on homosexuality in India.

Social Responsibilities Even when she became successful and rich, she ensured to channelize her earnings and wealth in the right direction. She set up Shakuntala Devi Education Foundation Public trust to guarantee that children who are living in an underprivileged family get better education. She stood as an epitome of a success of Indians in the field of Mathematics. Awards and Recognitions Being a mathematical genius, she was celebrated for her exceptional mathematical skills to devise answers easily.

She was honored with the Guinness Book of records on 18th June when she solved a multiplication problem of two randomly selected digit numbers. She arrived at the result in just 28 seconds. As I had no other money at home, I settled his account with the hundred rupee note I had found. Later I came to know that the plumber paid the note to his milkman to settle his monthly account, who paid it to his tailor for the garments he had had made.

The tailor in turn used the money to download an old sewing machine, from a woman who lives in my neigh- bourhood. This woman incidentally, had borrowed a hundred rupees from me sometime back to download a pressure cooker. She, remembering that she owed me a hundred rupees, came and paid the debt. I recognised the note as the one I had found on the footpath, and on careful examination I discovered that the bill was counterfeit.

How much was lost in the whole transaction and by whom? Tinku, Rinku and Jojo, the three brothers, divided the nuts in the following manner: As often as Tinku took four Rinku took three and as often as Tinku took six Jojo took seven.

With this data can you find out what were the respec- tive ages of the boys and how many nuts each got? We began to wonder how old the couple must have been each at the time of their marriage! Can you figure it out?

A wholesale merchant came to me one day and posed this problem. Every day in his business he has to weigh amounts from one pound to one hundred and twenty- one pounds, to the nearest pound. To do this, what is the minimum number of weights he needs and how heavy should each weight be7 I decided to send them through my boy servant Harish. On settlement Harish received Rs 2.

How many glasses did Harish break?

This num- ber is three times the sum of its digits. Can you find the number. Ten-of the ways have two figures in the integ- ral part of the number, but the eleventh expression has only one figure there. Can you find all the eleven expressions? One day a man walked in and slamming seventy- five paise on the counter requested, 'Please give me some 2 paise stamps, six times as many one paisa stamps, and for the rest of the amount make up some 5 paise stamps.

How would you have handled the situation? One day both of them were obliged to return home when each had thirty marbles unsold. They put together the two lots of marbles and handing them over to a friend asked her to sell them at five for 2 paise. According to their calculation, after all, 3 for one paise and 2 for one paise was exactly the same as 5 for 2 paise.

But when the takings were handed over to them, they were both most surprised, because the entire lot together had fetched only 24 paisel If however, they had sold their marbles separately they would have fetched 25 paise. Now where did the one paise go? Can you explain the mystery?

His wife drives him over to Howrah Station every morning and in the evening exactly at 6 P. One day he was let off at work an hour earlier, and so he arrived at the Howrah Station at 5 P.

He started walking home. They drove home arriving 10 minutes earlier than usual. How long did the man have to walk, before he was picked up by his wife?

At each of the 25 stations the passengers can get tickets for any of the others 24 stations. How many different kinds of tickets do you think the booking clerk has to keep? What is my aunt's share? Ws also have some beautiful bone-china saucers that I recently brought from Japan. Our table top is fifteen times the diameter of our saucers which are also circular. We would like to place the saucers on the table so that they neither over lap each other nor the edge of the table. How many can we place in this manner?

I did some quick cal- culations in my mind. I found that if I walk down twenty-six steps, I require thirty seconds to reach the bottom. However, if I am able to step down thirty-four stairs I would only require eighteen seconds to get to the bottom.

If the time is measured from the moment the top step begins to descend to the time I step off the last step at the bottom, can you tell the height of the stairway in steps?

Guittierez and Sr. Ibanez decided to have a Llama race over the mile course on the beach sands. They requested me and some of my other friends whom I had met at the resort to act as the judges. We stationed ourselves at different points on the course, which was marked off in quarter miles. But, the two Llamas, being good friends decided not to part company, and ran together the whole way.

How- ever, we the judges, noted with interest the following results: The Llamas ran the first three quarters in six and three quarters minutes. They took the same time to run the first half mile as the second half. And they ran the third quarter in exactly the same time as the last quarter.

From these results I became very much interested in finding out just how long it took those two Llamas to run the whole mile. Can you find out the answer? The numerals in each part in every case summed to a total of Can you show how the four parts of the clock face was broken? I decided to get only half the area of the window painted. Even after the painting I found that the clear part of the window still remained a square and still measured 4 feet from top to bottom and 4 feet from side to side.

How is it possible? One day he decided to sell them all and sold them to eight dealers. Each of the eight dealers bought the same number of animals and paid at the rate of Rs.
