For the following questions answer them individually

Question 21

In how many different ways can the letters of the word AUCTION be arranged in such a way that the vowels come together?

Video Solution

Solution

In the word : AUCTION", we have 4 vowels, i.e. A, U, I and O; let's consider them as 1 unit.

=> In total, we have1 unit + C + T + N = 4 units, which can be arranged in 4! ways, and the vowels themselves can be arranged in 4! ways

=> Required number of total arrangements is 4! * 4! = 24 * 24 = 576.

Question 22

The surface area of a cube is 1734 s.q. cm. Then volume of cube is.....

Video Solution

Solution

The surface area of a cube is given by $$6a^2$$ where 'a' is the side of the cube.

=> $$6a^2=1734$$

=> a = 17 units.

=> The volume of the square = $$a^3=17^3=4913$$ cube units.

=> Option-C

Question 23

$$\frac{x}{y} = \frac{1}{3}$$, then $$\frac{x^{2} + y^{2}}{x^{2} - y^{2}}$$

Video Solution

Solution

Given that x/y = 1/3 => y = 3x.

Substituting this in the given fraction, we get:

$$\dfrac{\left(x^2+\left(3x\right)^2\right)}{\left(x^2-\left(3x\right)^2\right)}=\dfrac{\left(10x^2\right)}{\left(-8x^2\right)}=-\dfrac{10}{8}=-\dfrac{5}{4}$$

=> Option-A

Question 24

How much time will it take for an amount ₹ 4.5% to yield ₹ 81 of interest at ₹ 4.5% per annum of simple interest ?

Video Solution

Question 25

The average of 7 consecutive numbers is 20. Then sum of smallest and greatest number is

Video Solution

Solution

We can assume the 7 consecutive numbers to be a-3, a-2, a-1, a, a+1, a+2, a+3

=> The sum of the numbers = 7a

=> The average of the numbers = 7a/7 = 20 => a = 20

The sum of the smallest and the largest number is a - 3 + a + 3 = 2a = 40.

=> Option-C

Question 26

Histone plays a major structural role in chromatin formation. A few exceptions, exist, most notably some sperm, where the histones are replaced by another class of basic protein named as

Video Solution

Question 27

Cetyl trimethyl ammonium bromide (CTAB) method is generally used for

Video Solution

Question 28

Entry of pollen tube into the ovule through funiculus or integuments is referred as

Video Solution

Question 29

The conventional ovule is lacking in the members of family

Video Solution

Question 30
