The chief component in the first generation computers are  Vacuum tubes.

Let the total book be 1

Then, in the 1st week 613th of book is read

i.e remaining pages =  1-613=713

in 2nd week he read 59th of it

i.e 59×713=35117
Remaining pages after 2nd week = 713-35117=28117

But given remaining pages after 2nd week = 100

28x117=100

--> x = 418 

 The total pages in the book are 418

A small organic molecule (sugars or amino acids), several of which may be bonded together to form a chain called a polymer.

Pollination by wind is called Anemophily or Wind pollination. The process of the transfer of pollen from one individual plant to another, whereby the pollen is carried by air currents is called Anemophily.

Almost all gymnosperms (Non-flowering plants) are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes.

loss % = common gain or loss102 %

           = (20/10)x(20/10)% = 4%

Here, k = 7 and l = 28
Therefore, first number = klx100 % of second number = 7/28 x 100% of second number = 25% of second number.

The third proportional of two numbers p and q is defined to be that number r such that

p : q = q : r.

Here, required third proportional of 10 & 20, and let it be 'a'

=> 10 : 20 = 20 : a

10a = 20 x 20

=> a = 40

Hence, third proportional of 10 & 20 is 40.
