Given series is 

12        16         32          68         ?

Here it follows a pattern that,

12

12 + (2x2) = 16

16 + (4x4) = 32

32 + (6x6) = 68

68 + (8x8) = 132

Let the total population be 'p'

Given ratio of male and female in a city is 7 : 8

In that percentage of children among male and female is 25% and 20%

=> Adults male and female % = 75% & 80%

But given adult females is = 156800

=> 80%(8p/15) = 156800

=> 80 x 8p/15 x 100 = 156800

=> p = 156800 x 15 x 100/80 x 8

=> p = 367500

Therefore, the total population of the city = p = 367500

Let number of boys in the school = x

Let number of girls in the school = y

Number of students participated in the sports = 300

Out of which boys = 100

but given number of boys participated in sports = x/3

=> x/3 = 100

=> x = 300

Remaining girls = 300 - 100 = 200

=> y/2 = 200

=> y = 400

Therefore, total number of students in the school = x + y = 300 + 400 = 700

Broadcaster Turner International India and Gujarat-based Rajgreen Group have entered into a brand partnership to set up India’s first Cartoon Network branded amusement park "Amaazia" in Surat, Gujarat.

The park is expected to be operational by the first quarter of 2019 on a budget of Rs. 450 crore. It will spread across an area of 61,000 sq m and will have family entertainment destination with 33 theme-based attractions as well as 20 unique water-slides. It will be divided into four major sections – a theme park branded by Cartoon Network, a water park, a family recreational hub and a service apartment and retail shopping area. The park has been conceptualised and designed by the Sanderson Group, Australia.

For Turner, this is the third such arrangement globally. It has a similar model in IMG Dubai and CN Amazone Water Park, in Thailand.

We know that,

The equivalent K =  L1 + L2L1K1+L2K2

where L1 & L2 are plate1 & Plate2 thicknesses, K1 & K2 are coefficient thermal conductivity of plate1 & Plate2 respectively.

But here L1 = L2 = L (say)

Then K = L+L/(L/K1 + L/K2)  =  2K1K2K1+K2

Let the ratio amount be 'p'

7p - 3p = 2700

4p = 2700

p = 675

R's Share = 675 × 6 = Rs. 4050
