The question is controversial, potatoes are more common than sweet potatoes, so it would make sense to understand it as potato and hence, the method of reproduction is tubers. The answer should be D.

Ans 7:

Let’s observe the first two sets of numbers (P and Q) carefully, and then try to find the missing number in the 3rd set (R). Let’s take Set P first. Let’s add all the numbers. 2 5 2 3 6 = 18 Now, let’s take Set Q. Again, add all the numbers. 7 4 3 5 2 = 21 Set Q – Set P = 21 – 18 = 3 That means there is a difference of 3 between the total of Set P and Set Q. We can suppose there will be difference of 3 between the total of Set Q and Set R. So, the total of Set R should be Set R – Set Q = 3 Set R – 21 = 3 Or, Set R = 3 21 = 24 Let’s add the numbers in Set R. 7 2 4 8 ? = 24 21 ? = 24 ? = 24 – 21 = 3 Hence, the right answer is Option B.

Ans 12:

Class : Class 3
Logic is - Central numbers are increasing in order .... 2...3...4 In first and second figures... Addition of left and right numbers = Addition of top and bottom numbers Means......... In fig1... 2+6 = 5+3 = 8 In fig2... 7+2 = 4+5 = 9 Therefore.... In fig3... 7+3 = 2+8 = 10 Hence the answer is B
