How many times should the keys of a type writer be pressed in order to type the first 299 natural numbers? (No spaces are left between the numbers)
To type singledigit natural numbers from 1 to 9, 9 keys must be pressed. To type twodigit natural numbers from 10 to 99, the keys of the typewriter must be pressed 90 x 2 = 180 times.
To type the 200 threedigit numbers from 100 to 299, the keys of the type writer must be pressed 3 x 200 = 600 times. Hence, the total number of times the keys of the type writer must be pressed = 9 + 180 + 600 = 789 „

The following question has a paragraph followed by four alternative ways of summarising the same. Choose the option that best captures the essence of the paragraph.
Within the last decade, there has emerged a second generation of “modernist’ critics which has been far less interested in sketching the broad outlines of a modernist movement; instead, they want to expose the diversity within “modernism’ and to explore ‘modernism’s’ institutional alliances and strategies.
That is, to what degree was “modernism" selfconsciously constructed by its practitioners and by its critics, and how did various social and market forces help shape the practices of “modernism"? Or, as the editors of Modem Art and Modernism phrase it, the task now is “to examine both the circumstances under which modem art has been produced, and those under which critical theories and forms of interpretation have themselves been produced."
a. The second generation of modernist critics that has become prominent during the last decade, has focussed on delineating the broad contours of the modernist movement. They have also attempted to shed light on the various influences on this genre.
b. A second generation of modernist critics that has emerged during the last decade, seeks to understand the diversity in modernism and the factors and circumstances underlying it.
c. A second generation of modernist critics as exemplified by the editors of ‘Modern Art and Modernism’ are attempting to understand the various market forces that have shaped modernism durina the last decade.
d. A second generation of modernist critics who have emerged during the last decade has attempted to selfconsciously construct modernism as done by its practitioners and critics. They have also attempted to outline the salient aspects of modernism.
The paragraph focusses on the area of study of modernist critics. They are interested in the diversity in modernism and how it came about. Choice (B) captures this. Choice (A) is factually incorrect and so is choice (D). Choice (C) is incomplete.
