Solution : Wednesday


Explanation:

Yesterday was Wednesday. Which means today is Thursday. 

Thursday Archie tells truth. Which means Archie's statement -'I lied yesterday.' is true. This supports the statement ' Archie lies on Monday, Tuesday and Wednesday and tells truth on other days'.

Kent lies on Thursday. So his statement 'I lied yesterday' is a lie. Which means he did not lie on Wednesday. This supports the statement 'Kent lies on Thursday, Friday and Saturday and tells truth on other days' .

 The question was  What is wrong with this proof ? a=b multiply both the sides by a     --1 a2 = ab  add -b2 to both the side           --2 a2-b2 =ab-b2  factorizing                                --3 (a+b)(a-b) = b(a-b)  divide both the sides by (a-b)    ---4 a+b=b Substituting a with b,              ---5 2b = b Dividing both the sides by b    ---6 2 = 1   The problem is with step 4. When a is equal to b, a-b is zero. You can not divide numbers by zero because division is only defined for non-zero numbers.
