Answer is 75.5
the reason is after adding you get, 75.513 which have 3 significant figures after the decimal..
But, of the given numbers 0.003 has 1 significant number after the decimal
So,you have to take total 1 significant number after the decimal and it becomes 75.5 (as after 5 you have 1 so no change)
