 Answer:

19 fishes

Step-by-step explanation:

Total spotted          Total stripped

      8                                    13

--------------------------------------------------------

Golden spotted              Golden stripped

      5                                0

--------------------------------------------------------

Spotted remaining          stripped remaining

3                                   13

Now Pink must be added in combination

1st combination    

Pink Spotted                Pink stripped

0                                          7  

--------------------------------------------------------

Spotted remaining          stripped remaining

3                                    6

[as 3 spotted fish are

remaining must be  

Stripes and spots

[MIX FISH]

on a single fish]  

                                (3 subtracted )

                               stripped remaining

                                          3

Total fishes= 5(Golden spotted) + 7(Pink stripped) + 3 MIX FISH + 3(stripped remain)= 18  

But 18 is not the option.

So  

2nd combination

Pink Spotted           Pink stripped

1                                  6  

--------------------------------------------------------

Spotted remain  stripped remain

2                                   7

These remaining 2

Must be spotted+ stripes

on single fish  

(subtracting it from remaining stripped)

                               now stripped remain  

                                              5

 

Total fishes = 5 (Golden Spotted) + 1 (Pink Spotted) +6 (Pink Stripped) + 5 (Stripped remain) + 2 MIX FISH

= 19 fishes
