Preface
“SSC Question Paper Set” is a penultimate weapon, designed to facilitate thorough preparation for
the students appearing for the SSC Board Examination. The book includes 15 Model Questions Papers across three subjects – 3 Solved Question Papers and 2
Practice Question Papers for each subject. These Question Papers are in tune with the changed syllabus and
are prepared based on the latest paper pattern. Additionally, 12 Board Question Papers (2015 and 2016) have
been included to gear up the students for the Examination. The Model Answer Papers offer complete answers
for every question with the relevant marking scheme to make sure the students encounter no scope for error. Solutions to Board Question Papers of 2015 and 2016 examinations are available in downloadable
PDF format at our website www.targetpublications.org. The purpose behind this is to make students familiar
with the current question paper pattern and marking schemes. It also gives them a holistic understanding of
the exact nature of the board question papers.
As the old adage goes, “Practice makes a man Perfect”, students will find here, a goldmine of
Question Papers to practice, before they are up for their final battle. We are sure these Question Papers will
prove to be extremely instrumental in achieving monumental scores in the Board Examinations.
The journey to create a complete book is strewn with triumphs, failures and near misses. If you think
we’ve nearly missed something or want to applaud us for our triumphs, we’d love to hear from you.
A book affects eternity; one can never tell where its influence stops.
We wish the students all the best for their examinations.
Yours faithfully,
Publisher.

i. Let the publisher printed x copies and cost of each copy be ` y.
amount invested by publisher = ` xy [1]
According to first condition,
(x + 2000) (y 5) = xy
xy 5x + 2000y 10000 = xy
5x + 2000y = 10000 ….(i) [1]
According to second condition,
(x 1600) (y + 10) = xy
xy + 10x 1600y 16000 = xy
10x 1600y = 16000 ….(ii) [1]
Multiplying equation (i) by 2 and then adding with equation (ii), we get
10x + 4000y = 20000
10x 1600y = 16000 2400y = 36000 y = 15 [1] Substituting value of y in equation (ii), we get 10x 1600 15 = 16000 x = 4000 Number of copies printed are 4000 and cost of each book is ` 15. [1] ii.
