Answer: (3) Rs,500
Explanation:-
Let the sum of money is Rs.X
Formula-
Simple Interest = P x R x T/100
Where, P – principal, R – rate  & T – time.
Simple Interest = Rs.70,  Time = 4 years, Rate = 3.5%  &   =  ?
Then,
70 = X x  35 x 4/10 x 100
70 = X x 7/10 x 5
10 = X / 50
X = Rs.500
Hence, the answer is (3) Rs.500.
