Can u find the numbers such that sum of every 2 and sum of all 4 may be perfect squares.
praveenscience
- Mar 12th, 2011
The four numbers are:
A. 10430
B. 3970
C. 2114
D. 386
Explanation:
A+B = 14400 = 1202
A+C = 12544 = 1122
A+D = 10816 = 1042
B+C = 6084 = 782
B+D = 4356 = 662
C+D = 2500 = 502
A+B+C+D = 16900 = 1302
Hope this is correct! :)

Length and Breath of Rectangle
The length and breath of of a rectangle is in the ratio 7:5.if the length decreases by 5 and the breath increases by 2,then the area of it was 65 sqkm.then find the actual length and breath of the rectangle.

- Jul 25th, 2009
The formula for area of rectangle is breath*length. It is given that l/b=7/5 From that l=7/5*bLength decreases by 5 and breath increases by 2.so now the new area will be A=(l-5)*(b+2)sub the value of...

Two concentric rings of uniform density at every point Are placed on a flat surface. Now since the centre of mass of a uniform Ring is its geometrical centre, the distance between the centers of Mass of the two rings are zero. Thus according to newtons law of Gravitation the attraction between themes (or at least tends to be) infinite, Making it impossible to pull one ring radially out from the other. However, as We know, this is not true. Why?

How come the inverse sguare law is not valid when distance tends to zero? Suppose if the distance is not zero,if it is of the order of 10^(-30) or above, even then the force is much greater. And comming to the nxt, the effective distance is considered b/w the 2 bodies.

Pythagorean triplets with Consecutive natural numbers
For readers interested in Pythagorean triplets with Consecutive natural numbers, take any odd number -- say 11 -- and square It. 11 squared = 121 = 2(60)+ 1. Add 60 squared to both sides to get 11 squared + 60 squared = 60 squared + 2(60) + 1 = (60 + 1) squared = 61 squared. What do we get? (11, 60, 61). Works every time. Prove it For a general case.

This is an overly simple algebra question. The first form of the equation is x^2 = 2y + 1. The second form of the equation is x^2 + y^2 = (y+1) ^2, which is just y^2 + 2y + 1. Subtract the y^2 from both sides of the equation and you again have x^2 = 2y + 1.

There was a robbery happened at a bank and 3 suspects taken into custody. Their statementsA: I am innocentB: I am innocentC: B did it.I didn\'t remember names, In these three one is lying and we have to find the culprit

The question is invalid. If only one is lying, then if A & B told the truth and C lied, C is the culprit. But if C told the truth, then A also told the truth and B is the one lying, so B would be the culprit. Bad question.

Suppose c is the culprit and liar.then both a and b are talking the truth,and c who is the culprit is telling the lie.

There are 3 persons sitting with the right hand of Ramesh
assume Ramesh=4
a=3
b=2
c=1
Ramesh gives 1 rs/- to a he has 3 left
now a has 4 and gives 2 to b remaining a has 2
now b has 4 and gives 3 to c remaining b has 1

In every 3 yrs it will be 1.5 times,there are 5 such sessions will come, amount after 3 yrs is (2000)*(1.5)amount after 6 yrs is ((2000)*(1.5))*(1.5)amount after 9 yrs is (((2000)*(1.5))*(1.5))*1.5=2000*(1.5)^3amount after 18 yrs is 2000*(1.5)^6=2000*11.390625=22781.25
