The correct option is
A 103To get 4 as the unit digit, the sum should be either
4 or
14.
But if R+E=14 ........... (1), then both of them should be greater than 5, because 9 is the greatest one digit number and if either of the R and E is 9 then next should be 5.
But at last we are getting 4, so R can't be greater than 4.
And thus, the sum of E and R should be 4.
So, sum of A and T should be 4.
Thus, R =4.
And E =0.
So either T and A are equal to 2 or either of the both is 3 or 4.
Thus, TEA stands for 103.
Hence, option A is correct.
