Which of the containers shown below will continue to have healthy fish and plants at the end of a week?

A
B
C
D None of these


Well actually, the *container* is too small for 3 fish. Those look like saltwater fishes, how do i know that water is mixed with salt. Saltwater fishes usually require tanks that are 10 gallon upwards for each fish, that one looks like 5 gallons. And to add, the fake plant, could hurt the fish if they graze against it, its not real because there is no substrate.

Two rows of numbers are given. The resultant number in each row is to be worked out separately based on the following rules. The operations on numbers progress from left to right.
Rules :
(i) If a two-digit odd number is followed by a prime number, the first number is to be multiplied by the prime number.
(ii) If an even number is followed by another even number, the first number is to be divided by the second number.
(iii) If an odd number is followed by a composite odd number, the first number is to be added to the second number.
(iv) If an even number which is a multiple of 5 is followed by another number which is again a multiple of 5, the second number is to be subtracted from the first number.
(v) If a number which is a perfect square is followed by another number which is also a perfect square, then the square roots of the two numbers is to be multiplied.
64 25 25
88 8 n
If n is the resultant of the first row, what is the resultant of the second row?

See just requires some thinking:Here in first Row 64 25 25 here 25 is following 64 and both are perfect squares so we apply rule v) and using that we will multiply the square roots of both 64 and 25 so 8 X 5 which is 40 now in first row we have got 40 25 now here 40 is an even number and a multiple of 5 even 25 is multiple of 5 so we can use rule iv) we subtract 25 from 40 and get 15 now this 15 is the n in second row so we get 88 8 15 now both 88 and 8 are even numbers so using rule ii) we do 88/8 which is 11 now we get in second row 11 15 now here 11 is odd number and 15 is composite number so using rule iii) we add 11 and 15 so we get 26 and hence that is answer.
