An industrial plant produces bottles. In 2001 the number of bottles produced by the plant was twice the number produced in 2000. How many bottles were produced altogether in the years 2000, 2001, and 2002?
Supoose:
Year 2000 bottles produced = X,
Year 2001 bottles produced= 2X.
Year 2002 bottle produced = ?
we need to find that
Year 2000 + Year 2001 + Year 2002 = Answer (?)A option says: In 2002 the number of bottles produced was 3 times the number produced in 2000. in year 2002 = 3X
Total
Year 2000 + Year 2001 + Year 2002 = Answer (3X) but what is X? (We dont know)
So, Answer can't be A or D
Come to 2nd option
n 2003 the number of bottles produced was one half the total produced in the years 2000 (X), 2001(2X), and 2002 (Suppose Y), hence year 2003 = (3X+Y)
Gives nothing to us hence ruled out B
By both options In 2003 the number of bottles produced was one half the total produced in the years 2000, 2001, and 2002. in 2003 = 3X. (That gives nothing to us, ruled out C)
Hence We are not able to calculate the total number of bottles produced 2000, 2001, 2002.
Answer: E
