A*A + B*B + C*C = D*D + E*E
A = 10 B=11 C=12 D=13 E=14
Let a, a+1, a+2. a+3 & a+4 be the numbers. a^2+(a+1)^2+(a+2)^2=(a+3)^2+(a+4)^2; solve this quadratic eqn. we get a=10 Numbers are 10 11 12 13 14
10, 11, 12, 13, 14
10*10 + 11*11 + 12*12 = 13*13 + 14*14 = 365
If abcde=1 (where a,b,c,d and e are all positive real numbers) then what is the minimum value of a+b+c+d+e?
A, B, C and D are four positive numbers such that A is 2/3 times of B, B is 5/6 times of C and C is 3/5 times of D. If the average of 3 times of A and 4 times of D is 900, then what is the average of all four numbers A, B, C and D?
