Heya,
Here is your answer.

[ good question, it take me half an hour!!]

☆ In this question, it's not saying about compound interest.

☆ But, normally, in compound interest questions, it is asked.

☆ I think compound annually is better because in that choice the man need to invest less compared to simple.

☆ We will have to do and prove both.

☆ COMPOUND YEARLY
A = P ( 1+%/100)^n
30,000 = P (1+8/100)^2
P = 30,000/1.1664
P = 25,720

☆ SIMPLE INTEREST
A = P+I
30,000 = P (1+2×8/100)
P = 30000/1.16
= 25, 860

☆ [ The ans I give above, is yearly, so, divide it By 12 to get monthly ]

☆ I will give compound monthly too. But, i don't think it may be useful.

☆ COMPOUND MONTHLY
A = P (1+R/100)^n
30,000= P (1+8/100)^24
30,000 = P× 6.34
P = 4730
Multiple of 5 = Rs.4730

Hope it helps..
