The monthly production of a commodity increases by 50% (over the previous month) every even month and drops by 20% (over the previous month) every add month. If the monthly production at the close of March was 1 ton, the production at the end of September will be approximately

Correct option is D

Given:
The monthly production follows a pattern:
Increases by 50% every even month (multiply by 1.5).
Decreases by 20% every odd month (multiply by 0.8).
The production at the end of March is 1 ton.
We need to find the production at the end of September.
Solution:
Starting with March = 1 ton:

April (Increase by 50%) → 1 × 1.5 = 1.5 tons
May (Decrease by 20%) → 1.5 × 0.8 = 1.2 tons
June (Increase by 50%) → 1.2 × 1.5 = 1.8 tons
July (Decrease by 20%) → 1.8 × 0.8 = 1.44 tons
August (Increase by 50%) → 1.44 × 1.5 = 2.16 tons
September (Decrease by 20%) → 2.16 × 0.8 = 1.73 tons
Thus, the production at the end of September is approximately 1.7 tons.

Final Answer:
(D) 1.7 tons
