Interest of 1 year = 920-880=Rs.40

Since, Principal = Amount - Interest

=> Principal (before 2 years) = $$880-40\times2=Rs.$$ $$800$$

=> Ans - (D)

All - T, F

No - T,T

Some - F,F

Some not - F,T

Some bags(F) are packets(F).

No packet(T) is a pouch(T)

Option A - No bag(T) is a pouch(T)   -> bag cannot be true

Option B - similar

Option D - Some bags(F) are not pouches(T) -> bag cannot be true

Hence option C 

First letter = F- G-H-I-J

Second letter = A-A-A-A-A

The pattern for 3rd letter is... every two consecutive letters are interchanged

G-F , I-H. Hence the next letter should be K

First letter pattern - E,G,I,K and M ( alternate letters)

Second letter pattern - LLLLL

Third letter pattern - FHJLN ( alternate letters)

K L L A

They toll together  after every LCM(2,4,6,8,10,12) seconds = 120 seconds

In 30 min, $$\frac{30\cdot60}{120}\ =\ 15$$

15+1 = 16 times
