ans is 11110
whenever we add any 2 no. in base 7 then the sum obtained is divided by 7, the remainder is the sum of the digit and the quotient is the carry
4+3=7 then seven divided by seven gives 1 carry and 0 remainder
now 3+4+1(carry) = 8 /7 = 1 quotient and 1 remainder
the rest can be obtained..

1234+6543 = 7777 in base 7
equivalent to 7 * 7^3 + 7 * 7^2 + 7 *7 + 7
= 7 (343+ 49 +7+1)
=7 *400 = 2800 ans
