There are two rows, each containing 3 numbers. Some rules are given below to be used for obtaining the resultant number for each row separately. Apply the rules for each row from left to right and answer the question. Rules: i. If an even number is followed by an even number, the first is to be subtracted from the second. ii. If an odd number is followed by an odd number, both are to be added. iii. If an odd number is followed by an even number, the even number is to be subtracted from the square of the odd number. iv. If an even number is followed by an odd number, the odd number is to be subtracted from the even number. Row I: 28, 19, 12 Row II: 13, 7, 32 What is the average of the resultant numbers of the first row and the second row?

Row I: 28, 19, 12 Row II: 13, 7, 32 What is the average of the resultant numbers of the first row and the second row? Correct Answer 40.5

Given Rows 

Row I: 28, 19, 12

Row II: 13, 7, 32

Using the above rules The Row 1 can be 

Row I: 28, 19, 12, From left to right the even number followed by odd number. So, use the rule iv

⇒ (28 - 19) = 9

Row I: 9, 12 From left to right the odd number followed by even number. So, use the rule iii

⇒ (9² - 12) 

⇒ 81 - 12 = 69

Row I= 69

Using the above rules The Row 2 can be 

Row II: 13, 7, 32 From left to right the odd number followed by odd number. So, use the rule ii

⇒ (13 + 7) 

⇒ = 20

Row II: 20, 32 From left to right the even number followed by even number. So, use the rule i

⇒ (32 - 20)

⇒ = 12

Row II = 12

Average of Row I and Row II are = (69 + 12) ÷ 2

⇒ 81 ÷ 2

= 40.5

Hence, "40.5" is the answer.

Given below are three quantities named 1, 2 and 3. Based on the given information, you have to determine the relationship between the three quantities. You should use the given data and knowledge of Mathematics to choose between the possible answer. Quantity 1: Area of the innermost square. A square is made by joining the midpoints of a square of area 200 sq. m. The outermost square is called Square 1, The square inside it is called Square 2. The next square is made by joining midpoints of square 2 and is called Square 3. This process goes on. Square 5 is the innermost square. Quantity 2: A man starts with a speed of 10 km/hr. He increases his speed by 10 km/hr every hour at the start and drives at the same speed for that hour. If he traveled a total distance of 550 km. Find the time Quantity 3: Height of cylinder Its volume is equal to the volume of a cone whose radius is 14 cm and height is 39.3 cm. The radius of the cylinder is 14 cm

Study the given information carefully and answer the question that follows. In a boat, people are sitting in two parallel rows, with five people each in a row, in such a way that there is equal distance between adjacent persons. In the first row, Mani, Nani, Alex, Puri and Tuli are seated (not necessarily in the same order) and all of them are facing south. In the second row, Sharma, Atkin, Putin, Neha and Priya are seated (not necessarily in the same order) and all of them are facing north. Therefore, people in the opposite rows face each other in this arrangement. Priya sits third to the right of Atkin. Atkin sits at one of the extreme ends. Sharma sits second to the left of Priya. The person facing Sharma sits to the immediate right of Nani. Puri sits second to left of Nani. Mani is not an immediate neighbour of Nani. Only two people sit between Mani and Alex. Neither Nani nor Mani faces Neha. Who among the following is facing Tuli?
