The present ages of three persons in proportions 4 : 7 : 9. Eight years ago, the sum of their ages was 56 Find their present ages (in years).1. 20, 35, 452. 16, 28, 363. 8, 20, 284. 8, 14, 18

Answer» Correct Answer - Option 2 : 16, 28, 36

Given:

The ratio of present ages of three persons are in the ratio 4 : 7 : 9

8 years ago sum of their ages were = 56

Calculation:

Let us take the ratio of ages be 4x, 7x, 9x respectively

Ages of the person before 8 years = (4x - 8), (7x - 8), (9x - 8)

According to the question

⇒ (4x - 8) + (7x - 8) + (9x - 8) = 56 

⇒ 20x - 24 = 56

⇒ 20x = 80  

⇒ x = 4

Substituting the values in ratio

⇒ 4 × 4 : 7 × 4 : 9 × 4 = 16 : 28 : 36

∴ The present ages of 3 persons are 16, 28, 36

Why there is lack of atmosphere on the surface of moon?

Answer»

Our Moon doesn't have an atmosphere because it is too small and doesn't have a strong magnetic field. Any atmosphere it might have had would be stripped away by the solar wind that barrages the small world. In contrast, our planet has more mass to hold its atmosphere close, and a strong magnetic field to protect it.

Calculate the de Broglie wavelength of a neutron of kinetic energy 150 eV. mass of neutron = 1.67 × 10–27 kg.

Answer»

De Broglie wavelength λ = h/√2mEk

Here EK = 150 eV = 150 × 1.6 × 10–19 J = 2.4 × 10–17 J

∴ λ = 6.63 x 10-34/√[2 x 1.67 x 10-27 x 2.4 x 10-17] m= 2.335 x 10-12 m

= 0.02335 Å

The runs scored in a cricket match by 11 players are as follows:16, 9, 15, 18, 50, 100, 102, 14, 20, 80, 5. Let x, y, and z be the range, mean and median respectively of this data. If x = y + z + p, then the value of p is1. 422. 433. 584. 40

Answer» Correct Answer - Option 4 : 40

Given:

The runs scored in a cricket match by 11 players as follows

16, 9, 15, 18, 50, 100, 102, 14, 20, 80, 5

Mean of data = y

Range of data = x

Median of data = z

Concept used:

The range is the spread of your data from the lowest to the highest value in the distribution. The range is calculated by subtracting the lowest value from the highest value. 

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the middle number in a data set when the numbers are listed in either ascending or descending order. 

Calculations:

Mean y = (16 + 9 + 15 + 18 + 50 + 100 + 102 + 14 + 20 + 80 + 5)/ 11

⇒ 429/11 = 39

The highest value in the given data = 102

The lowest value  in the given data = 5

Range x = 102 - 5

⇒ 97

Now arrange the data in ascending order:

5, 9, 14, 15, 16, 18, 20, 50, 80, 100, 102

⇒ Median = middle value = 18 (Since total numbers are odd)

 x = y + z + p

⇒ 97 = 39 + 18 + p

⇒ p = 97 - 39 - 18

⇒ p = 40

∴ Th required value of p is 40

29.

Find the missing value of p for the distribution whose mean value is 14?X589p1215f810127561. 402. 423. 484. 52

Answer» Correct Answer - Option 2 : 42

Given:

Mean of the given data is 14 and data along with the frequency is given

Formula Used:

Direct formula for mean \(= {\rm{}}\sum {{\rm{f}}_{\rm{i}}}{{\rm{x}}_{\rm{i}}}/\sum {{\rm{f}}_{\rm{i}}}\)

Calculation:

Here we need to calculate the value of \({f_i}{x_i}\) and \({f_i}\) and the missing value be p

\({{\bf{x}}_{\bf{i}}}\)

\({{\bf{f}}_{\bf{i}}}\)

\({{\bf{f}}_{\bf{i}}}{{\bf{x}}_{\bf{i}}}\)

\(\sum {{\bf{f}}_{\bf{i}}} = 48 + {\bf{p}}\)

\(\sum {{\bf{f}}_{\bf{i}}}{{\bf{x}}_{\bf{i}}} = 378 + 7{\bf{p}}\)

 

Now, Put these value in the given formula

∴ 14 = (378 + 7p)/48

⇒ 672 = 378 + 7p

⇒ p = 42

Hence, option (2) is correct

30.

Find the median for the following frequency distribution?X1357911131517f812711109151161. 72. 93. 114. 13

Answer» Correct Answer - Option 2 : 9

Given:

Following observation table is given along with frequency

Formula Used:

To calculate median we always need to calculate the cumulative frequency so when discrete data is given then we find the cumulative frequency just greater than (N/2)

Where, N = ∑f

Calculation:

To calculate the median we have to calculate cumulative frequency first

N = ∑f = 89

 

 

∴ N/2 = 89/2 = 44.5

So, 44.5 lie in 45 and the value of x corresponding to 48 is 9

∴ Median is 9

Hence, option (2) is correct

31.

Find out the median of values of this set 11.1, 12.1, 11.5, 11.9 and 12.31. 11.12. 11.53. 11.94. 12.1

Answer» Correct Answer - Option 3 : 11.9

Given:

Values of set 11.1, 12.1, 11.5, 11.9 and 12.3

Concept used:

Median = middle value of the set 

Calculations:

Arrange the values of set in ascending order 

Arranged set = 11.1 11.5 11.9 12.1 12.3 

Median = 11.9 (middle value of the set)

∴ Median of this set is 11.9

32.

Find out the median of this data 1, 2, 5, 6, 9, 20, 12, 23 and 11 .1. 12. 53. 94. 11

Answer» Correct Answer - Option 3 : 9

Concept used :

The median is the middle number in a data set when the numbers are listed in either ascending or descending order.

If total number of observation (n) is odd then, Median = (n + 1)th/2 observation

If total number of observation (n) is even then, Median = [(n/2)th + (n/2 + 1)th]/2 observation

Calculations :

Arrange this data in ascending order 

Arranged data = 1, 2, 5, 6, 9, 11, 12, 20, 23

n = 9 which is odd

Median = (9 + 1)/2 = 5th observation

5th observation of the data is 9

∴ Median = 9 (middle value of the set)

Median of this set is 9 

 

33.

There are 5 boys, whose height are 70, 73, 74, 67 and 65 cm respectively, then find out the median of the height.1. 652. 673. 704. 73

Answer» Correct Answer - Option 3 : 70

Given :

There are total 5 boys 

Their heights are 70, 73, 74, 67 and 65 cm 

Concept used :

Median = Middle value of the set 

Calculations :

Arranging the heights in ascending order 

Arranged set = 65, 67, 70, 73 and 74

Median = 70 (middle value of the set)

∴ Median of the set is 70 cm

A first order reaction takes 40 min for `30%` decomposition. Calculate `t_(1//2)`. (Given `log 7 =0.845)`A. `33.2 m i n `B. `77.7 m i n`C. `22.7 m i n`D. `40 m i n `

Answer» Correct Answer - 2
`30%` decomposition means that `x=30%` of `a=0.30a`
As reaction is of 1st order,
`k-(2.303)/(t)log.(a)/(a-x)=(2.303)/(40 min )log.(a)/(a-0.30a)=(2.303)/(40)xxlog.(10)/(7)"min"^(-1)`
For a 1st order reaction
`t_(1//2)=(0.693)/(k)=(0.693)/(8.918xx10^(-3)"min"^(-1))=77.7min`

A wooden block performs SHM on a frictionaless surface with frequency, `v_0`. The block carries a charge +Q on its surface. If now a uniform electric field `vecE` is switched-on as shown, then the SHM of the block will be A. of the same frequency and with shifted mean positionB. of the same frequency and with the same mean positionC. of changed frequency and with shifted mean positionD. of changed frequency and with the same mean position

Answer» The frequency will be the same `v=sqrt(k//m)//2pi`. Frequency is independent of any external constant. But due to the constant foce `q//E` toward right, the equilibrium position gets shifted by `qE//K` in forward direction.

Two vehicles, each moving with speed `u` on the same horizontal straight road, are approaching each other. Wind blows along the road with velocity `w`. One of these vehicles blows a whistle of frequency `f_(1)`. An observer in the other vehicle hears the frequency of the whistle to be `f_(2)`. the speed of sound in still air is `V_C`. The correct statement `(s)` is (are)A. If the wind blows from the source to the observer, `f_2 gt f_1`B. If the wind blows from the observer to the source, `f_2 gt f_1`C. If the wind blows from observer to the source, `f_2 lt f_1`D. If the wind blows from the source to the observer, `f_2 lt f_1`

Answer» Correct Answer - A::B
If wind blows from source to observer
`f_(2)=f_(1)((V+w+u)/(V+w-u))`
When wind blows from observer towards source
`f_(2) =f_(1) ((V-w+u)/(V-w-u))`
In both cases, `f_(2) gt g_(1)`.
