The Correct Option is A
Solution and Explanation
Let's take the number of articles produced per day be x and the number of days be d.
dx = 360 – Equation (1)
now,
(d-1) × (4+x) = 360
4d + xd -4 -x = 360
4d + xd -x = 364
4d - x = 364 - 360 = 4
4d -x = 4 – Equation (2)
After solving the equations 1 and 2, we get
d = 10 days.
The correct option is (A):
dx = 360 – Equation (1)
now,
(d-1) × (4+x) = 360
4d + xd -4 -x = 360
4d + xd -x = 364
4d - x = 364 - 360 = 4
4d -x = 4 – Equation (2)
After solving the equations 1 and 2, we get
d = 10 days.
The correct option is (A):
