## Case study based  The students of a school can stand in two ways, in circles or in row. In case of circles: there are 23 students in the first circle, 21 in the second, 19 in the third and so on. There are 5 students in the last inner most circle. How many circles are there? In case of rows: 20 students are there in the first row, 19 in the second row, 18 in the next row and so on. If 5 students are there in the top most row. It was observed that students were talking with one another when they were made to stand in the circular pattern. Therefore, the teacher chose to make them stand in rows. (a)If the students are standing in circles then the number of students standing in 5th circle is (A) 17 (B) 16 (C) 15 (D) 14 (b) If the students are standing in circles then the number of circles is (A) 5 (B) 10 (C) 15 (D) 20 (c) If the students are standing in rows then the number of students standing in 7th row is (A) 14 (B) 16 (C) 15 (D) 13 (d) If the students are standing in rows then the number of rows is (A) 14 (B) 15 (C) 16 (D) 17 (e)Total number of students standing in rows is (A) 100 (B) 200 (C) 150 (D) 250

## solve the case study There are two cottage industries A and B having the same number of employees. In industry A, It was observed on a particular day the cost of production of each toy (in rupees) was 3 more than twice the number of toys produced on that day. If the total cost of production on that day was ₹90, find the number of toys produced. In industry B, the cost of production of each toy (in rupees) was found to be 6 more than four times the number of toys produced on that day. On a particular day the total cost of production was ₹550. Using the above information answer the following case study questions. (a)If the number of toys produced in A be ‘x’ then cost of production of each toy is ( in rupees ) (A) 2x + 3 (B) 3x + 2 (C) x(2x + 3 ) (D) 2x2 + 3 (b)The number of toys produced in industry A on that particular day is (A) 2 (B) 3 (C) 6 (D) 5 (c) If the number of toys produced in B be ‘y’ then, cost of production of each toy is ( in rupees ) (A) y(4y + 6) (B) 4y + 6 (C) y(6y+4) (D) 4y2 + 6 (d)The number of toys produced in industry B on that particular day is (A) 10 (B) 12 (C) 11 (D) 4 (e)The number of toys produced in industry B than industry A on that particular day is (A) 4 (B) 5(C) 6 (D) 7
