Answers
Given : A manufacturer of laptop produced 6000 units in 3rd year and 7000 units in 7th year
production increases uniformly by a fixed number every year
To Find : the production in the 5th year
Solution:
Let say fixed number increased every year = d
Manufactured in 3rd Year = 6000
Manufactured in 4th Year = 6000 + d
Manufactured in 5th Year = 6000 + d + d = 6000 + 2d
Manufactured in 6th Year = 6000 + 2d + d = 6000 + 3d
Manufactured in 7th Year = 6000 + 3d + d = 6000 + 4d
6000 + 4d = 7000
=> 4d = 1000
=> d = 250
=> 2d = 500
Manufactured in 5th Year = 6000 + 2d
= 6000 + 500
= 6500
