Explanation for question No 1


jQuery UI Accordion - Default functionality
Cost of 6 bottles packaged water = $14.76
Cost of 1 bottle packaged water = 14.76/6
                                              = 2.46
Cost of 48 bottles = 48 x 2.46
                          = $ 118.08
So the correct answer for this question is $118.08 option B


Explanation for question No 2


jQuery UI Accordion - Default functionality
Add -37 and -42
= -37 + (-42)
Since we have same symbol for both the numbers we have to add them,and we have to put negative symbol for the answer.
= - 79 So the correct answer for this question is -79 option B


Explanation for question No 3


jQuery UI Accordion - Default functionality
To find the maximum capacity of container.
We have to find H.C.F for these numbers.
850 = 5 x 2 x 17 x 5
850 = 52 x 2 x 17
680 = 5 x 2 x 17 x 2 x 2
680 = 5 x 23 x 17
H.C.F = 5 x 17 x 2
= 170 liter
So the correct answer for this question is 170 liter option A


Explanation for question No 4


jQuery UI Accordion - Default functionality
To find the time, when they will all change simultaneously, we have to find the L.C.M of (48,72,108).
L.C.M of (48,72,108) is 432 seconds = 7 min 12 sec
So, after every 7 min 12 sec, all the signals will change simultaneously.
At 8:20:00 hrs, if all the three signals change simultaneously, again they will change simultaneously after 7 min 12 sec. That is at 8:27:12 hrs.
Hence, three signals will change simultaneously at 8:27:12 seconds.
So the correct answer for this question is 8:27:12 hrs option A


Explanation for question No 5


jQuery UI Accordion - Default functionality
The plane flies 4000 km in 5 hours
From this we are going to find how far does it fly in 1 hour.
For that we have to divide 4000 by 5
The height of the plane reached by the plane in 1 hour = 4000/5
                                                                               = 800 km
So,the height covered by the plane in 3 hours = 800 x 3
                                                                    = 2400 km
So the correct answer for this question is 2400 km hrs option A


Explanation for question No 6


jQuery UI Accordion - Default functionality
Total number of students in the class = 1000
Out of 1000 students 28% of students are girls
So,numbers of girls = 28 % of 1000
                         = (28/100) x 1000
                         = (28 x 10)
                         = 280
So the correct answer for this question is 280 option C


Explanation for question No 7


jQuery UI Accordion - Default functionality
Marks obtained by Peter = 285
Total marks allotted for the examination = 500
To find percentage of marks obtained by Peter = marks obtained by peter/Total marks
                         = (285/500)
                         = 0.57
To convert this into percent we have to multiply it by 100.
So,0.57 x 100 = 57 %
Therefore percentage of marks obtained by Peter = 57%
So the correct answer for this question is 57% option B


Explanation for question No 8


jQuery UI Accordion - Default functionality
To find the value of a2- 2 (b2 + c2)
we have to apply 2 for a,3 for b and and 1 for c
                         = 22 - 2 (32 + 12)
                         = 4 - 2(9 + 1)
                         = 4 - 2(10)
                         = 4 - 20
                         = -16
So the correct answer for this question is -16 option A


Explanation for question No 9


jQuery UI Accordion - Default functionality
Straight angle So the correct answer for this question is Straight angle option A


Explanation for question No 10


jQuery UI Accordion - Default functionality
Length of the rectangle = 16 cm
Breadth of rectangle = 8 cm
Perimeter of rectangle = 2 (length + breadth)
                = 2 (16 + 8)
                = 2 (24)
                = 48 cm
So the correct answer for this question is 48 cm option C
