Answer: (1) 1380
Explanation:-

12 carpenters  workings 6 hours a day can make 460 chairs in 24 days.
12 carpenters can make chairs in a day = 460/ 24
A carpenter can make chairs in an hours = 460/12 x 24 x 6 = 115/24 x 6 x 3
18 carpenters ca make chairs in 36 days each working 8 hours daily =  18 x 36 x 8 x 115 /24 x 6 x 3
= 1380

Hence, the answer is (1) 1380.
