Question 4
1 / -0

The total agricultural land in a village is $$1200$$ hectares. This is distributed among $$320$$ families who form four groups in the following pattern. It is assumed that the land is distributed equally within each group. Identify the group of small farmers
Group Number of families Total amount of land owned and operated

C 30 300
D 10 300

A
A

B
B

C
C

D
D

Solution

In group of small farmers, it would be minimum land available to each farmer.
So we will find the ration of total amount of land owned and operated by each group to the number of families.
From A, $$\dfrac {300}{100} = 3$$
From B, $$\dfrac {300}{180} = 1.67$$
From C, $$\dfrac{300}{30} = 10$$
From D, $$\dfrac {300}{10} = 30$$
B is the group of small farmers.
Option B is correct.
Question 5

An ascending curve

B
A descending curve

C

Directions For Questions

A car is going on a long journey for $$16$$ hours, starting at $$5.00$$ hrs. The speed of the car at different hours is given.

...view full instructions

From the table, answer the following question.
The percentage of decrease in speed during $$19.00$$ hrs and $$21.00$$ hrs is ____________.
Time(in hrs) $$5$$ $$7$$ $$9$$ $$11$$ $$13$$ $$17$$ $$15$$ $$19$$ $$21$$
Speed (in km/hour) $$40$$ $$50$$ $$60$$ $$80$$ $$70$$ $$65$$ $$75$$ $$60$$ $$50$$

A
$$\displaystyle 16\frac{1}{3}\%$$

B
$$\displaystyle 16\frac{2}{3}\%$$

C
$$\displaystyle 17\frac{2}{3}\%$$

D
$$\displaystyle 18\frac{2}{3}\%$$

Solution

Speed at $$19.00$$ hrs.$$=60$$ km/hr
And speed at $$21.00$$ hrs.$$= 50$$ km/hr
Thus, $$\% $$ decrease $$=\dfrac{60-50}{60}\times 100=16\dfrac{2}{3}\%$$
Question 8
1 / -0

The line graph shows the amount of water used by Jamie from March to July. Express the amount of water used in June as a fraction of the total amount of water used.

A
$$\displaystyle \frac{3}{14}$$

B
$$\displaystyle \frac{1}{7}$$

C
$$\displaystyle \frac{2}{7}$$

D
$$\displaystyle \frac{3}{140}$$

Solution

Total amount of water used = $$20+15+30+40+35=140$$L
Amount of water used in june=$$40$$L
Amount of water used in June to the total amount of water=$$\dfrac{40}{140}=\dfrac{2}{7}$$
Question 9
1 / -0

The given pictograph shows the number of students of class V participated in different games at Annual Diwali Mela. How many more students participated in ring the prize than in estimating weight and knock the stuff toy altogether?

A
$$51$$

B
$$96$$

C
$$42$$

D
$$83$$

Solution

Number of students who participated in estimating weight = $$17 \times 3 = 51$$
Number of students who participated in knock the stuff toy = $$17 \times 3 = 51$$
So, total number of students who participated in estimating weight and throwing the ball altogether = $$51+51=102$$
Now, number of students who participated in ring the prize = $$17 \times 9= 153$$
$$\therefore$$ Required difference = $$153-102=51$$
Question 10
1 / -0
