A) 1 B) 0
C) 10 D) 5
 
Answer & Explanation Answer: A) 1

Explanation:

From the given data,

11+ 11 = 4 => 1 + 1  +  1 + 1 = 4

12 + 12 = 6 => 1 + 2  + 1 + 2 = 6

13 + 1 3 = 8 => 1 + 3  + 1 + 3 = 8


Similarly,

how_tall_is_the_table1542200476.jpg image

A) 40 cm B) 150 cm
C) 120 cm D) 45 cm
 
Answer & Explanation Answer: B) 150 cm

Explanation:

Let the heights of Cat, Table and Turtle be C, T & R respectively.

 

From the above given figure,

 

C + T - R = 170 ......(a)

 

R + T - C = 130 ......(b)

 

Adding above eqns (a) & (b), we get

 

2T = 300

 

T = 150 cm

 

Hence, the height of the table is 150 cm.

Q:

Solve the number puzzle

number_puzzle1540890829.jpg image

A) 2 B) 3
C) 0 D) Can't be determined
 
Answer & Explanation Answer: B) 3

Explanation:

In the given number puzzle,

Sum of Row 1 = 14

Sum of Row 2 = 23

Sum of Row 3 = 13 + ?

 

Sum of Column 1 = 16 

Sum of Column 2 = 23 

Sum of Column 3 = 11 + ?

 

Diagonal 1 sum = 17

Diagonal 2 sum = 14 + ?

 

From the above analysis,

Sum of Row 2 = Sum of Column 2 = 23

Sum of Row 1 = Sum of Column 3 = 14 = 11 + ?    .............(1)

Sum of Row 3 = Sum of Column 1 = 16 = 13 + ?    .............(2)

Diagonal 1 sum = Diagonal 2 sum = 17 = 14 + ?    .............(3)

  

Hence,

From (1), (2) & (3)

? = 3

Q:

A tennis ball machine serves a ball vertically into the air from a height of 2 feet, with an initial speed of 110 feet per second. After how many seconds does the ball attain its maximum height?

A) 2.87 sec B) 3.44 sec
C) 4.65 sec D) 5.41 sec
 
Answer & Explanation Answer: B) 3.44 sec

Explanation:

It is launched vertically with an initial speed of 110 ft/sec.

It will reach maximum height when the speed drops to 0.

Vo=110 feet per second 

ho=2 feet 

So, h(t) = -16t^2 +110t +2 

Take the derivative: h'(t) = 110 -32t 

The maximum height will be at the inflection when the derivative crosses the x-axis, then h'(t)=0. 

So, set h'(t)=0 and solve for t: 

0 = 110 -32t 

-110 = -32t 

t=3.4375 

t=3.44 seconds.
