Students are made to stand in rows. If one student is extra in a row there would be 2 rows less. If one student is less in a row there would be 3 rows more. Find the number of students in the class.
Ans: No. of rows be y
Let the number of students be x
Number of students in the class will be = xy
One student extra, 2 rows less
(x + 1) (y - 2) = xy
xy - 2x + y -2 = xy
-(-2x + y -2) = 0
+2x - y = -2 -------------- (1)
One student less, three more rows
(x - 1) (y + 3) = xy
xy + 3x - y -3 = xy
3x - y = 3 ---------------------(2) From (1) & (2)
2x - y = -2 X 3
3x - y = 3 X -2
Solve it , to get ... y = 12 and x = 5
∴ Number of student = xy
= 12 X 5
= 60 students
It's easier to describe an explicit solution, in this case and then tell you what an implicit solution is not, and after that provide you an illustration to demonstrate you the dif
Determine or find out if the following series converges or diverges. If it converges find out its value. Solution We first require the partial sums for this series.
Solve by factorization X 2 +(a/a+b + a+b/a)x+1 = 0 X 2 +(a/a+b + a+b/a)x+1 => X 2 +(a/a+b x a+b/ax + a/a+b .a+b/a) => X[x+a/a+b] +a+b/a[a+a*a+b]= 0 => X= -a
