192000 Rs.

With compound interest=r, 12000[1+(r/100)]^5=24000, [1+(r/100)]^5=2
As [1+(r/100)]^20=[1+(r/100)]^5*4=2^4=16
So 12000[1+(r/100)]^20=12000*16=192000

Mr. Decimal enters a lucky draw that requires him to pick five different integers from 1 through 31 inclusive. He chooses his five numbers in such a way that the sum of their logarithms to base 10 is an integer. It turns out that the winning 5 numbers have the same property, i.e. the sum of their logarithms to base10 is also an integer. What is the probability that Mr. Decimal holds the winning numbers?

In Loonyville, four people called Doctor, Engineer, Lawyer and Architect follow the professions of doctor, lawyer, engineer and architect. However, none of them follow the profession indicated by their name. Doctor plays bridge very regularly, as he thinks it as an intellectual card game.

the complete series is divided into 2 series like

the difference between the numbers in second series is 9
So the next number in the series must be 91+9=90

Let A can finish a work in x days then B will finish it in 2x days
Thus 1/x + 1/2x = 1/18

Let for n years he paid interest 7.5%
and for (21-n) years interest paid was 7%
so,
((180000*n*7.5)/100) + ((180000*7*(21-n))/100) = 270900
solving it we get n=7
so for 21-7 = 14 years he paid the reduced interest

april =30 days
may =31 days
june =30 days

hence ,total day in a year =365

Job Role : To Increase Customer By Doing Survey of Newspaper.
Organization : Dainik Bhaskar
Duration : 4 months
Project Profile :
Mega: Rotational Visual Cryptography using Basic (2, 2) Scheme.
Description: This scheme is used for hiding two halftone secret images into two meaningful shares Created from halftone cover images. Using Human Visual System, again the four secret images can be easily recovered by placing the two shares on top of each other with different angles. Rotation Visual Cryptography using basic (2,2) scheme which encrypts three secret images into three shares and each secret image can be easily revealed by overlaying one share with the 1800 anticlockwise rotation of another share. In this way the combination of any of the two shares reveals one secret image with the help of 1800 anticlockwise rotation. The reconstructed original three secret images have the same contrast as achieved in the basic visual cryptography scheme (2, 2).

Mini: Traffic Road Sign Detector used to alert the Driver of the vehicle about the Road Sign by Detecting the Traffic Signs of the Road.
Description: A vision-based vehicle guidance system for road vehicles can have three main roles: (1)
road detection; (2) obstacle detection; and (3) sign recognition. The first two have been studied for many years and with many good results, but traffic sign recognition is a less-studied field. Traffic signs provide drivers with very valuable information about the road, in order to make driving safer and easier. It has two main parts. The first one, for the detection, uses color thresholding to segment the image and shape analysis to detect the signs. The second one, for the classification, uses a neural
network.

LET X BE THE TYM TAKEN BY A TO FINISH THE WORK.THEN, B TAKES 10 DAYS MORE, SO X+10
NOW, 1:3 :: X:X+10

Here,

Three people check into a hotel.

They pay £30 to the manager and go to their room.

The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people.

On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person.

Now each person paid £10 and got back £1.

So they paid £9 each, totalling £27. The bellboy has £2, totalling £29.

Where is the missing £1?

Reply Like? Yes | No

neha gupta 10 years ago

Let the numbers be a and b
a + b = (1/3) of (1/5) of 195 = 39
a * b = (1/6) of (1/4) of 960 = 40
solving a+b =39 and ab = 40
we get a quadratic equation a2 - 13a +40 =0
its solution is a=5,8
for this correspondingly b = 8,5
their difference:
a=8 , b=5 , a-b=3 so 1/3 of difference is 1
a=5 , b=8 , a-b= -3 so 1/3 of difference is -1
