The price of the book is marked 20% above the C.P. If the marked price of the book is Rs. 180, then what is the cost of the paper used in a single copy of the book?

Rs. 36
Rs. 37.50
Rs. 42
Rs. 44.25

Correct Answer

A. Rs. 37.50

Explanation

Clearly, marked price of the book = 120% of C.P. Also, cost of paper = 25% of C.P Let the cost of paper for a single book be Rs. n. Then, 120 : 25 = 180 : n => n = Rs. (25x180)/120 = Rs. 37.50 .

If 5500 copies are published and the transportation cost on them amounts to Rs. 82500, then what should be the selling price of the book so that the publisher can earn a profit of 25%?

Rs. 187.50
Rs. 191.50
Rs. 175
Rs. 180

Correct Answer

A. Rs. 187.50

Explanation

For the publisher to earn a profit of 25%, S.P. = 125% of C.P. Also Transportation Cost = 10% of C.P. Let the S.P. of 5500 books be Rs. x. Then, 10 : 125 = 82500 : x => x = Rs.(125x82500)/10= Rs. 1031250. Therefore S.P. of one book = Rs. 1031250/5500= Rs. 187.50 .

1996 and 1998
1997 and 1998
1995 and 1996

Correct Answer

A. 1995 and 1996

Explanation

Total exports of the three Companies X, Y and Z together, during various years are: In 1993 = (30 + 80 + 60) = 170 In 1994 = (60 + 40 + 90) = 190 In 1995 = (40 + 60 + 120) = 220 In 1996 = (70 + 60 + 90) = 220 In 1997 = (100 + 80 + 60) = 240 In 1998 = (50 + 100 + 80) = 230 In 1999 = (120 + 140 + 100) = 360 Clearly, the total exports of the three Companies X, Y and Z together are same during the years 1995 and 1996.

7.

Average annual exports during the given period for Company Y is approximately what percent of the average annual exports for Company Z?

87.12%
89.64%
91.21%
93.33%

Correct Answer

A. 93.33%

Explanation

Analysis of the graph: From the graph it is clear that 1. The amount of exports of Company X (in Pesetas) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 30, 60, 40, 70, 100, 50 and 120 respectively. 2. The amount of exports of Company Y (in Pesetas.) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 80, 40, 60, 60, 80, 100 and 140 respectively. 3. The amount of exports of Company Z (in Pesetas) in the years 1993, 1994, 1995, 1996, 1997, 1998 and 1999 are 60, 90,, 120, 90, 60, 80 and 100 respectively. Average annual exports (in Pesetas) of Company Y during the given period = 1/7 x (80 + 40 + 60 + 60 + 80 + 100 + 140) = 560/7= 80. Average annual exports (in Pesetas) of Company Z during the given period = 1/7 x (60 + 90 + 120 + 90 + 60 + 80 + 100) = (600/7 ) . Therefore Required percentage = [(80)/(600/7) * 100]=93%
