• If the letters of the word UNIVERSITY are arranged in alphabetical order then we get the following:
  • E I I N R S T U V Y
• The seventh letter from the left end is T as shown below -
  • E I I N R S T U V Y

Hence, "T" is the correct answer.

Given equation: 16 + 6 ÷ 18 - 5 × 1 = 14.

BODMAS Table:

Let's check each option one by one.

Option 1) 5 and 16

Given: 16 + 6 ÷ 18 - 5 × 1 = 14

After interchanging the numbers we get;

⇒ 5 + 6 ÷ 18 - 16 × 1 = 14

⇒ 5 + 0.33 - 16 × 1 = 14

⇒ 5 + 0.33 - 16 = 14

⇒ 5.33 - 16 = 14

⇒ - 10.67 ≠ 14

⇒ LHS ≠ RHS

Option 2) 14 and 18

Given: 16 + 6 ÷ 18 - 5 × 1 = 14

After interchanging the numbers we get;

⇒ 16 + 6 ÷ 14 - 5 × 1 = 18

⇒ 16 + 0.43 - 5 × 1 = 18

⇒ 16 + 0.43 - 5 = 18

⇒ 16.43 - 5 = 18

⇒ 11.43 ≠ 18

⇒ LHS ≠ RHS

Option 3) 5 and 14

Given: 16 + 6 ÷ 18 - 5 × 1 = 14

After interchanging the numbers we get;

⇒ 16 + 6 ÷ 18 - 14 × 1 = 5

⇒ 16 + 0.33 - 14 × 1 = 5

⇒ 16 + 0.33 - 14 = 5

⇒ 16.33 - 14 = 5

⇒ 2.33 ≠ 5

⇒ LHS ≠ RHS

Option 4) 18 and 6

Given: 16 + 6 ÷ 18 - 5 × 1 = 14

After interchanging the numbers we get;

⇒ 16 + 18 ÷ 6 - 5 × 1 = 14

⇒ 16 + 3 - 5 × 1 = 14

⇒ 16 + 3 - 5 = 14

⇒ 19 - 5 = 14

⇒ 14 = 14

⇒ LHS = RHS

Hence, the correct answer is "Option 4".

A botanical garden is a garden dedicated to the collection, cultivation, preservation and display of a wide range of plants labelled with their botanical names. In short it doesn’t contain all the natural resources, but only plants. So, assumption 1 is not implicit.

The second assumption provides the information regarding why the trip is being conducted, i.e., ‘students are likely to understand more by interacting with a new environment’. Hence, assumption 2 is implicit.

The given statement is: Z < R = W ≥ P = Q > T

Conclusions:

I. Q < Z → False (as Z < R = W ≥ P = Q gives either Z < W or W ≥ Q and no definite relation between Q and Z can be determined).

II. R > T → True (as R = W ≥ P = Q > T given; as R ≥ P and P > T so R > T is true).

Hence, the correct answer is “Only conclusion II is true”.

Statement 1:

Mr. Z had reached the railways station at 10 am

Statement 2:

There is a train at 11 am and the next train is at 12 pm

From given information, it is clear that Mr. Z have to wait 1 hour for the next train.

Both statement 1 and 2 are sufficient.

The number triangles in the figure are shown below:

  Hence, '18' is the correct answer.

The mirror image of the given figure is:

The shaded part in Venn Diagram represents only Science and History.

The number represents only Science and History is: 6

Hence the correct answer is "6".
