The no. of boys speaking only hindi = 12% of 3/8 of 400= 18
The no. of boys speaking both Hindi and English = 6*18= 108
The total no. of boys speaking Hindi = 126

24% speak only Hindi i.e 96 speak Hindi.

12% of 150 boy i.e 18 boys speak only Hindi

Of these 18 boys speak only Hindi and hence remaining 76 are girls speaking only hindi

24% speak only Hindi.
Hence remaining 76% must speak English or English and Hindi both.
Total number of students = 400
76% of 400=304
Hence, option A is correct.

Total number of students who speak only Hindi=24% of 400 = 96

Number of boys who speak only Hindi = 12% of 150 = 18

Number of girls who speak only Hindi = 78

The percent of girls speaking only Hindi  of the total number of students speaking only Hindi = $$\frac{78}{96}\times100$$ = 81.25

Number of girls speaking both the langauge = (400- no. of boys speaking both language)- No. of girls speaking only english - No. of girls speaking only hindi = 400 - 108 - 44-96 =117

The ratio = 108/117

Let the length be L and breadth bhe B.
Now Diameter of circle is equal to the Length.
And it's radius is equal to breadth.

Here, radius of circle is = 14

Hence, Length = 28

Breadth = 14

Area = 28*14=392

Female Population = Total Population - Male Population

Now, Average =(Total number of females)/number of cities

                       =$$\frac{6.5+7.8+6.0+6.0+9.1+11.2}{5}$$

                       = 8.32

The increase in production = $$\frac{1300-1100}{1100}\times100$$

                                           = 18.18%

No. of students not preferring Maths or Economics = No. of students preferring History or Geography

 = (Percent of students preferrig history + Percent of students preferrig history)% of 550

  = 72% of 550 = 396

Average = (8.5+7.6+12.8+5.4+10.5)/5 = 8.96

Difference between the lowest and average = 8.96-5.5 = 3.46
