**Directions (1-5): Study the following information carefully to answer the following:**

Rajaji college has five different types of groups, Maths, Physics , Chemistry, Commerce and computer . The total number of students are 2000. One-fourth of the total number of students are Commerce . 10% of the total students are Chemistry students . 25% of the total students are Physics. Remaining Students are either Computer or Physics students . The number of Physics Students are 120 more than the number of students of computer.

- If 20% of commerce students are failed , what is the number commerce students are passed?
500400300200100Option B

Number of Maths students =25 x 2000/100 = 500

Number of Commerce students = 2000 x1/4 = 500

Number of Chemistry students =10 x2000 /100 = 200

Number of computer + Physics students = 2000 – ( 500 +500 + 200) = 800

Number of computer students + no.of computer students +120 =800

2( number of computer students ) = 800 – 120 = 680

Number of computer students = 680/ 2= 340.

Number of physics students = 120 + 340 =460Number of commerce students = 500

Failed = 20% of 500 = 20/100 x 500 = 100

So, number of students passed = 500 – 100 = 400. - What is the ratio of the total number of Commerce students to the total number of Students in computer and physics students together?

1:53:45:86:35:9Option C

Ratio of commerce and ( computer + physics)= 500 🙁 340 +460 )

= 500: 800 = 5:8 - What is average of the total number of students in computer, Chemistry and Commerce students together?
456.8234.8346.7123.6236.9Option C

Average = (500 + 200 + 340 ) / 3 = 346.7 - What is the difference between the total number of students in computer and maths students together and the number of Physics students?

280380480580680Option B

Difference = ( computer + maths) – physics

= ( 340 + 500 ) – 460 = 380 - The number of Chemistry students are approximately what percent of the total number of maths students and commerce students together?

1020304050Option BNumber of maths + commerce = 500 + 500 =1000.

Number of Chemistry students = 200

percentage = 200/ 1000 x 100 = 20% - Total no. of Social books sold in B, D and E is what percentage of total English books sold in these schools?

56.5%34.90%65%45%78.47%Option E

Total Social books sold in B, D and E together

= 40,000 + 5,000 + 10,000 = 55,000

Total English books sold in these schools together

= 30,000 + 20,000 + 20,000 = 70,000

Required percentage = (55,000/70,000) × 100 = 78 .47% - What is the total profit earned on Science book from B, C and E if cost price of one Science book is Rs. 120 (in Rs. lakhs)
Rs. 52,80,000Rs. 22,80,000Rs. 12,80,000Rs. 70,80,000Rs. 2,80,000Option B

Total profit earned =25,000×120×40/100+20,000×120×30/100+15,000×120×20/100

= Rs. 22,80,000 - If Rs.120 is the cost price of Social book , then what is the total selling price of this book earned from A, C and D together (in Rs. Lakhs )?
79 , 20, 00060 , 20, 00059 , 20, 00079 , 45, 00079 , 40, 000Option A

Selling price earned from School A = 30,000 × 120 × 140/100 = 50, 40,000

Selling price earned from School C= 15,000 × 120 × 120/100 = 21, 60, 000

Selling price earned from School D= 5,000 × 120 × 120/100 = 7,20,000

Total selling price earned = 79 , 20, 000. (add all selling prices) - If one Social book, one Science book and one English book is costs Rs. 150, Rs. 120 and Rs. 100 respectively then total selling price of these three books in School D is what percent more or less than the total selling price of these three books in School E (Nearest integer)?
56789Option B

Total selling price of all the three books in School D =5,000×150×120/100+20,000×120×125/100+20,000×100×110/100=61,00,000

Total selling price of all the three books in School E =10,000×150×130/100+15,000×120×120/100+20,000×100×120/100=65,10,000

Required percentage =(65,10,000-61,00,000 )/ 65,10,000 × 100 = 6% less - What is the average number of Science books sold in five schools together?
510152025Option D

Required average no. of Science books

= (20 + 25 + 20 + 20 + 15) /5 = 100 / 5 = 20
