A) 6500 units
B) 5000 units
C) 6000 units
D) 8000 units
Correct Answer: A
Solution :
Since, production of Laptops in 3rd year = 6000 \[\Rightarrow \] \[{{a}_{3}}=6000\] \[\Rightarrow \] \[a+2d=6000\] .... (I) Also production of laptops in 7th year = 7000 \[{{a}_{7}}=7000\Rightarrow a+6d=7000\] ?.. (ii) Subtracting (i) from (ii), we get \[4d=1000\,\,\,\Rightarrow \,\,\,d=250\] From (i), \[a+2(250)=6000\,\,\,\Rightarrow \,\,\,a=5500\] Hence, production in fifth year \[{{a}_{5}}=a+4d=(5500+4\,(250))=6500\]unitsYou need to login to perform this action.
