<h2>Given :-</h2>
- 50 men do 10 hours work daily complete work in 20 days
- 80 men do job in 50% time
- Days required
- 1 man may do job in (50 × 20) days =
- 1 man may do job in 1000 days
Now,
- 80 man = 1000/80 = 12.5
Now,
- When hours reduced 50% then we will multiply days by 2
- Total days = 12.5 × 2 = 25 days.
- Option C is correct
Answer:
2304
Step-by-step explanation:
<u>Given :- </u>
- A geometric sequence is given to us which is 9 , -18 , 36.
And we need to find out the 9th term of the sequence. Here firstly we should find the Common Ratio and then we can substitute the respective values in the formula to find the nth term of a geometric sequence .
<u>Common Ratio :- </u>
CR = -18÷ 9 = -2
<u>The </u><u>9</u><u> th term :- </u>
T_n = arⁿ - ¹
T_9 = 9× (-2) ⁹ - ¹
T_9 = 9 × (-2)⁸
T_9 = 9 × 256
T_9 = 2304
<u>Hence the 10th term is </u><u>2</u><u>3</u><u>0</u><u>4</u><u>.</u>
