BITSAT Logical Reasoning Test - 1 - JEE MCQ

Given: Rate of sulphur on the earth = 5 parts out of 2250 parts.
Percentage of sulphur in the earth

Given : length of train, I = 50 m; Length of platform, d = 100 m, and time, t = 10 sec.
Total distance covered by the train to pass the platform, s = I + d
= 50 + 100 = 150 m.

Given, tax per rupee = 10 paise = 0.1 rupee and total paid tax = 18.25 rupees.
Total amount on which tax is paid

= 0.0156 + 2 = 2.0156

The difference of each successive and previous numbers has the sequential increase of one as
3 - 1 = 2 , 6 - 3 = 3, 10-6=4, 15-10=5,
21-6 = 1 5 ,2 8 -7 = 2 1,36-8 = 2 8 ,4 5 - 9 = 36 
(i.e. 2, 3, 4, 5, 6, 7, 8, 9)
Therefore next number after 15 in the series will be 21 (i.e. 21 - 1 5 = 6).

The third and fifth numbers are the multiple of 4 of the first and third number respectively. Therefore next number in the series will be (i.e. 128) multiple of 4 of the fifth number 32 x 4 = 128.

Each alphabet of UKPI is the next alphabet of SING. Therefore TAKE will be written asVCMG.

Each alphabet XBUFS is the next alphabet of WATER. Therefore SALT will be written as TBMU.

‘A’ and ‘E’ are husband-wife and B, G and C are their children. ‘H’ is the father of ‘E . Therefore ‘H’ is the grandfather of ‘C.

‘D’ is the husband of ‘B\ And C, B and G are the brother and sisters. Therefore ‘D’ is the brother-in-law of ‘C’.

• According to the question, we have to find out the odd figure from the given four figures.
• Here, we can see that in all the figures a square box is given, and a symbol is inside each box.
• By comparing all the symbols we can say that all the boxes have punctuation symbols, but the second box contains a mathematical operator. 
  Hence, the correct answer is 
  

Given matrix:

Here, we have to find out the number that will replace the question mark.
In the figure, we can observe the following pattern by which the numbers are written.
20  = (21+1) − 2
23 = (22+2) − 1
43 = (?+5) – 2
⇒? = 40
So, 40 is the missing number.
Hence, this is the correct answer.

Given figure:

Here, we have to find out the total number of straight lines in the given figure.
From the given figure, a total number of horizontal lines=3.
The total number of vertical lines = 0
A total number of slant lines leaned towards the right side, and another 3 leaned towards the left side = 6
Therefore, the total number of lines = 3 + 6 = 9.
Hence, the correct answer is 9.
The concepts used in this question are

The figure can have vertices and points where straight lines cut named as shown below.

So, the triangles are
△ABI , △ABH , △ABG , △ABF , △AIH , △AIG , △AIF , △AHG ,
△AHF , △AGF , △ABC , △ACD , △ADE , △AEF , △ACJ , △AEJ ,
△CDE , △CJD , △EDJ , △BCI , △EFG , △ACE .
Thus, this is the correct answer.

According to the given figure:
The numbers in the triangle adjacent to the rectangular block, when added to thrice the number which is adjacent to that particular triangle in the anticlockwise direction, will result in the number in the rectangular block:
⇒ 1 + 4 × 3 = 13
⇒ 2 + 1 × 3 = 5
⇒ 3 + 2 × 3 = 9
Let us consider the unknown number to be x. By applying the above pattern, we get:
⇒ x = 4 + 3 × 3 = 13
⇒ x = 13
Hence, the correct answer is 13.

Figure given in the question:

The paper is folded first and second along inclined axes and at last folded along horizontal axis.
The mirror image along horizontal axis :

The mirror image along inclined axes :

This is similar to the image given in option C.
Hence, the cut paper will appear as figure given in option C when opened.

Given figures:

Here, we can see in the given figure four triangles are present.
So, the required answer figure must contain the same number of triangles as in the question figure.
Thus, the figure that consists of all the pieces given in the question is as follows:

Hence, this is the correct answer.

We have to fold the sheet as given in the question figure and punch the shaded parts.

After unfolding the paper, the punched portions will be visible as shown below: 

The paper has been cut thrice at the longest edge, once at each of the shorter edges, and once in the middle of the triangular sheet.
So, the first option is the correct answer.

When we fold and punch the paper as indicated in the question (step 1 to step 4 in the above image), and then we unfold the paper, we will get the pattern as shown in Step 6.
The shape of the punched hole will be a single rectangle, which is positioned in the middle of the paper such that it is symmetric about the fold lines.
Hence, option D is the correct answer.
