Explanation: Kashish is 5th from left and Mona is 13th from left. This means Mona is 8 positions ahead of Kashish.
Mona’s position from right = 6
So, Kashish position from right = 6 + 8 = 14
It will be Mona’s position from right after interchange of positions.

Explanation: When 27 is divided by 3, we get 9 as quotient.

Explanation: The following table gives the explanation.

 M L K J I H G F E D C B A 13 12 11 10 9 8 7 6 5 4 3 2 1 4 3 2 1 13 12 11 10 9 8 7 6 5

Explanation: Age of mother = M
Age of husband = H = M + 9
Age of Son = S = M/2
Age of Daughter = D = F/3
Also, D = S – 7
Or, S – 7 = F/3
Or, 3S – 21 = F
Or, 3(M/2) – 21 = F
Or, (3M/2) – 21 = M + 9
Or, 3M – 42 = 2M + 18
Or, 3M = 2M + 60
Or, M = 60

Explanation: Rs. 96 is divisible by all the options. Let us solve by using option a, i.e. 8
If 8 people attended the picnic then per head cost = Rs. 12
If 8 + 4 people will attend the picnic then per head cost = Rs. Rs. 8
Difference is of Rs. 4
Hence, option a is the right answer.

Explanation: This can be solved by using the following Venn Diagram.

Explanation: This question can be solved by using the following Venn Diagram.

Explanation: The name of vegetable is PUMPKIN

Explanation: Let us try to solve this by using the smallest option, i.e. 10
Number of Hens = 10
Number of Cows = 10
Number of Bullocks = 5
Total animals = 25
Hence, number of keepers = 3
Number of heads = 25 + 3 = 28
Number of legs = 10 × 4 + 5 × 4 + 10 × 2 + 3 × 2 = 40 + 20 + 20 + 6 = 86
Difference between number of legs and number of heads = 86 – 28 = 58

Now, let us solved this by using the second smallest option, i.e. 12
Number of Hens = 12
Number of Cows = 12
Number of Bullocks = 6
Total animals = 30
Hence, number of keepers = 3
Number of heads = 30 + 3 = 33
Number of legs = 12 × 4 + 6 × 4 + 12 × 2 + 3 × 2 = 48 + 24 + 24 + 6 = 102
Difference between number of legs and number of heads = 102 – 33 = 69
Hence, option c is the right answer.
