Answer 2

Hence all options are correct.

Given: The ratio of accounts of all banks = 4:5:7

To Find: From the following options which cannot be number of active accounts.

Solution:

Let active accounts in Bank A is =  4k

Let active accounts in Bank B is =  5k

Let active accounts in Bank C is =  7k

So, the total number of active accounts should be

= 4k + 5k + 7k

= 16k

Now, as the number of accounts cannot be in fraction or decimal so the value of k should be in whole number.

Checking option A

16k = 80000

k = 5000

As k is whole number so this is correct option.

Checking option B

16k = 96000

k = 6000

As k is whole number so this is correct option.

Checking option C

16k = 48000

k = 3000

As k is whole number so this is correct option.

Checking option D

16k = 56000

k = 3500

As k is whole number so this is correct option.

Hence all options are correct.
