type 3: question no. 2
Sir answer is correct but if I'm not wrong the method is not completely right. principal should be (20)^4= 160,000 and then we proceed further in usual manner

That is different method.

@akanksha Mishra I went with that earlier method and I got the same answer but the thing is you need to be very careful while assigning interest on interest..
well this compound tree has 4 levels
1st level sum = 32,000
2nd level sum = 2400
3rd level sum = 80
4th level sum = 1
there fore C.I = 34481 units
as principal is (20)^4 = 160000units
and p= 8000rs
160000 units = 8000rs
1 unit = 1/20
now C.I = 34481 units
= 34481x(1/20)
C.I = 1724.05
AND the 1st level sum is nothing but your simple interest
S.I = 32000 units
= 32000 x(1/20)
= 1600 Rs
now the difference part
CI - SI = 1724.05 - 1600.00
= 124.05 Rs
therefore, both the methods leads to the same answer
thank you

if you are going by the earlier method then the division would be
34481/20 = 1724.05

as per the second approach the principle should be 20*20*20*20.... and by 1st approach how can we find the difference of CI & SI
