Answer:
6117.76
Explanation:
hello rausha let's see the explanation step by step-
first we know the simple interest of money per annually is 7%
so the interest of the money in 3 years must be 21%
now we will takeout 21% of 7744 = 1626.24
this means the interest gained is 1626.24
to takeout original sum of money we will subtract the interest from $7744 ( 1626.24 - 7744) = 6117.76
so the original sum of money which was deposited was 6117.76 .
