Answer : 2. "17.5 days"
Explanation :

Answer: B) 17.5 days Explanation: Let the number of days be 'p'  As the work is same, we know that M1 x D1 x H1 = M2 x D2 x H2 Where M = Men, D = Days, H = Hours per day  Here M1 = 9, D1 = 15, H1 = 7  M2 = 6, D2 = p, H2 = 9  => 9 x 15 x 7 = 6 x p x 9  => p = 35/2 = 17.5 days.
