120 (1-1/2)(1-1/3)(1-1/5) = 32 numbers
(x+y)(x-y) = 343 possible solutions 343*1 49*7 Hence value of x+y is a or b
(a+1)^3 - a^3 = 1027 3a^2+3a+1 = 1027 3(a^2+a) = 1026 a^2 +a = 342 a(a+1) = 342
ab= 10a+b ba = 10b+a sum = 11a+11b = 11(a+b), since it is a perfect square, hence a+b = 11 possible values (65, 74, 83, 92) only difference 0f 65 ...
