See, first 702rs pw is calculated for 6 months and second 702rs pw is calculated for 1 year because 6months + 6months = 1year i.e., we have to calculate the present worth in present the question is like divide the sum by 2 and calculate the pw of firtst half in 6 months and pw for 2nd half for 6 months.
For 2nd half we should consider 1year because when you think wrt pw it becomes 1year. Hope all of you can get.

Why second time we take only 702 if we consider time as 1 year?

Since it is in SI, only that interest part will be added in each 6 months. So, what is the need for 1year in the second part?

hi,
In the above problem first half-yearly 702 and second half yearly 702+first half yearly i.e., 1year so in the second bracket, it is taken as one year.
A=p+S.I.
A=P+(PTR/100),
A=P(1+TR/100),
SO Coming To The Problem,
for first half-yearly,
(100*702/100+8*1/2),
For second Half Yearly,
(100*702/100+8*1).

Yeah, it should be 1/2 even in the second bracket I guess because it is the equal half yearly basis.
