Let Priyatham's age = x

Then, Vishal's age = 2x; Raghu's age = x/2; Veeru's age = 4x ; Karthik's age = x/4

So, the descending order of ages is :

Veeru > Vishal > Priyatham > Raghu > Karthik

Therefore,  Karthik is the youngest.

Golden Rice (Oryza sativa) denotes a genetically modified rice capable of biosynthesizing and accumulating β-carotene (provitamin A) in the endosperm, yielding a characteristic yellow color in the polished grains. Golden rice was developed to help cope with vitamin A deficiency, a problem that prevails in developing countries, affecting millions (Underwood, 2000; UNICEF, 2000). Vitamin A deficiency causes mortality and growth retardation in children and frequently impairs vision, leading to blindness. It also contributes indirectly to anemia by interfering with iron bioavailability.

The endosperm of Golden Rice (Oryza sativa) is yellow due to the accumulation of β-carotene (provitamin A) and xanthophylls. The product of the two carotenoid biosynthesis transgenes used in Golden Rice results in Pale Yellow color.

Here in 100P2, P says that permutations and is defined as in how many ways 2 objects can be selected from 100 and can be arranged.

That can be done as,

100 P2 = 100!/(100 - 2)!

= 100 x 99 x 98!/98!

= 100 x 99 

= 9900.

Productivity is a result of the way that a business operates – the result of the way that its people, business processes, different functional units and suppliers come together to meet the needs and wants of its customers.

Productivity is the combination of intelligent planning and focused efforts and hence, it is a combination of Efficiency and Effectiveness.

Efficiency is an internal measure of performance for companies that shows how well the company converts inputs into outputs. The more the ratio of outputs to inputs approaches 100 percent, the better the efficiency of the process will be. In simple terms, it is “doing things right” and comes from proper harnessing of time, cost and efforts.

Effectiveness :

Organizational effectiveness is an external measure of performance and indicates how well an organization fulfills the demands of various organizational stakeholders. Simply put, it is “doing the right things."

The cow can graze an area of 2826 sq.m i.e it is able to cover area of circle of 2826 sq.m

Therefore, πr2 =2826
r2 =(2826×7/22) = 899.18 = 900
r = 30 m.

Therefore, the radius of the circle implies the length of the rope = 30 mts.
