$$36.5^{0}C$$
0%
$$33.5^{0}C$$
Explanation
The temperature at 1:30 PM will be $$36.5^oC$$; The point between 1 p.m. and 2 p.m. on the x-axis is equidistant from the two points showing 1 p.m. and 2 p.m., so it will represent 1.30 p.m. Similarly, the point on the y-axis, between $$36^oC$$ and $$37^oC$$ will represent $$36.5^oC.$$

The class marks of a frequency distribution are given as follow 15,20,25,...
The class corresponding to the class mark 20 is
Report Question

$$12.5-17.5$$
0%
$$17.5-22.5$$
0%
$$18.5-21.5$$
0%
$$19.5-20.5$$
Explanation
Width=5
Class marks=20
$$\therefore Lower\ limit=20-\dfrac{5}{2}$$
$$\Rightarrow \dfrac{40-5}{2}=\dfrac{35}{2}=17.5$$
$$Upper\ limit=20+\dfrac{5}{2}$$
$$\Rightarrow \dfrac{40+5}{2}=\dfrac{45}{2}=22.5$$
Hence the class corresponding to the class mark 20 is $$17.5-22.5.$$
Class mark of a particular class is 6.5 and class size is 3 then class interval is:
Report Question
0%
$$5-8$$
0%
$$6.5-9.5$$
0%
$$3.5-6.5$$
0%
$$4-7$$
Explanation
Let the a be the lower limit of the class interval
Class size of the class interval =3
$$\therefore$$ Upper limit of the class interval$$=a+3$$
Class mark=6.5
$$\therefore \dfrac{a+a+3}{2}=6.5$$
$$\Rightarrow 2a+3=6,5\times 2$$
$$\Rightarrow 2a=13-3$$
$$\Rightarrow 2a=10\Rightarrow a=\dfrac{10}{2}=5$$
$$\therefore a+3=5+3=8$$
Hence class interval= $$5-8$$

Dealer A sold 40 Maruti cars less than dealer B
0%
Dealer B sold 50 Maruti cars more than dealer C
0%
Dealer B sold the most number of Benz cars
0%
The total number of Benz cars by dealers Band C is 15
Explanation
Let us investigate the options in relation to the given bar graph.
Option A$$\longrightarrow $$A sold 30 Maruti cars and dealer B sold 50 Maruti cars.
So the difference $$=50-30=20$$.
$$\therefore $$ Option A is false.
Option B$$\longrightarrow $$B sold 50 Maruti cars and dealer C sold 25 Maruti cars.
So the difference $$=50-25=25$$.
$$\therefore $$ Option B is false.
Option C$$\longrightarrow $$ B sold 5 Benz cars and dealers A &C sold 10 Benz cars each.
$$\therefore $$ Option C is false.
Option D$$\longrightarrow $$ B sold 5 & C sold 10 Benz cars.
So B & C sold total 15 Benz cars.
$$\therefore $$ Option D is correct.
