Explanation
- Find a positive number which when increased by 17.
- Is equal to 60 times the reciprocal of the number.
- The number can be figure out in this way.
Let suppose the positive number is y.
60 times the reciprocal of the number
60 x 1/y
Positive number when increased by 17
y + 17 = 60 x 1/y ________ (i)
Through equation (i) we can easily find out the value of y (y = 3).
To Find
Number = ?
Solution
Let suppose
Number = y
According to the given condition
y + 17 = 1/y x 60
y(y + 17) = 60
y2 + 17y = 60
y2 + 17y – 60 = 0
y2 + 20y – 3y – 60 = 0
y(y + 20) – 3(y + 20) = 0
(y + 20)(y – 3) = 0
y + 20 = 0 & y – 3 = 0
y = -20 (not possible) & y = 3 (possible)
Required Number = 3 answer
Conclusion
Find a positive number which when increased by 17 is equal to 60 times the reciprocal of the number. The number is 3 which is the required answer.
