@Tejaswini.
S.I = p * t * r/100.
A = P + S.I.
= P + P * T * R/100.
= P(1 + T * R/100).
= P(100 + T*R/100).
So, P = (100 * A/100 + T * R).
S.I = p * t * r/100.
A = P + S.I.
= P + P * T * R/100.
= P(1 + T * R/100).
= P(100 + T*R/100).
So, P = (100 * A/100 + T * R).

First half year includes months i.e. 1/2 but second half early = 6+previous 6 months i.e. 1/2+1/2 = 1.

What is 100*702/(100+8*1/2)?

Since 8*(12/12)=8*1
8*(6/12)=8*(1/2)
8*(6/12)=8*(1/2)
