distinct aitE..no solution
a^3 + b^3 = c^3 + d^3 -->(1)
a+b = c+d --> (2)
solving (1) and (2)
ab = cd -->(3)
solve (2) and (3)
ab = c(a+b-c) => c^2 -(a+b)c + ab = 0
==> c = a or b
hence no solution..

Annapurna Garu .. along with a*b = c*d ; u should also staisfy a+b = c+d and I am not getting any solution there ..
Yeha Aruna garu .. Zero emo anipistondi gaani we never know sinc eit is not necessary that a<b<c<d they can be any numbers
for instance
say a=2; b=6 and c=3; d=4
Isnt it very close?

The number of three digit numbers with different digits formed by using the digits 2,3,4,5,6,7 such that the middle digit is the largest digit is????
Posted by: Aruna At: 16, Dec 2005 5:34:06 PM IST
I think she meant distict a,b,c and d
so we need to find a, b, c, d such that
a+b = c+d and also a*b = c*d
Are there any numbers?
