Question

Find a positive number which when increased by 5 becomes equal to 50times of its reciprocal

Answer 1

Let the +ve number be x.
According to question,
x+5=50/x
x2 + 5x = 50
x2 + 5x - 50 = 0
x2 + 10x - 5x - 50 = 0
x(x+10) - 5(x+10) = 0
(x-5) (x+10) = 0
(x-5) = 0 ; (x+10) = 0
x= 5 or x= -10

Value of x cannot be -10 as it is given in question that the number is positive, so the required positive number is 5.

I think u get help from this solution......

Answer 2

Answer:

The x will be 5 and -10

x=5 and x= -10

so as per the question no negative values should be taken so the answer will be 5

So when the number 5 is increased by 5 becomes equal to 50 times of its reciprocal
