1.  There are five bags. In the first bag we put some fruits. Each bag the number of fruits is reduced by 1/4. The last bag contains 4. Then the number of fruits in the first bag is ?
A. 2596
B. 1024
C. 256
D. 64

Answer: Option B

Explanation:

Fruits reduced by 1/4.

Total no. of bags N = 5

Formula to find no. of fruits in 1st bag = 4^n

Last Bag = 4 fruits.

That means, 4th bag = 4 x 4 = 16 fruits

3rd bag = 16 x 4 = 64 fruits

2nd bag = 64 x 4 = 256 fruits

1st bag = 256 x 4= 1024 fruits.
