Consider the no. of years to be 1/2. and solve it in the usual way.
Let the sum be Rs. 100. Then,
S.I. for first 6 months = Rs. [100 x 10 x 1/2]/100= Rs. 5.
S.I. for last 6 months = Rs.[105 x 10 x 1/2]/[100]= Rs. 5.25
So, amount at the end of 1 year = Rs. (100 + 5 + 5.25) = Rs. 110.25.
Effective rate = (110.25 – 100) = 10.25%.
I hope this helps!
