2 Men or 5 Women or 8 children completes a work in equal time. If one Man completes a work in 33 days. Then working together 1 man, 1 Woman and 1 Child will complete the whole work in how many days? 2 पुरूष या 5 महिलायें या 8 बच्चे किसी कार्य को समान समय में समाप्त करते है। यदि एक पुरूष पूरे कार्य को 33 दिनों में समाप्त करता है तो एकसाथ कार्य करते हुये 1 पुरूष, 1 महिला तथा 1 बच्चा पूरे कार्य को कितने दिनों में समाप्त करेंगे?

2 men = 5 women = 8 children in terms of work completion time. If 1 man completes work in 33 days, then 2 men complete it in 33/2 = 16.5 days. Work rate: 2 men do 1/16.5 work per day. So 5 women do 1/16.5 work per day, meaning 1 woman does 1/(16.5 × 5) = 1/82.5 work per day. Similarly, 8 children do 1/16.5 work per day, so 1 child does 1/(16.5 × 8) = 1/132 work per day. Combined rate of 1 man + 1 woman + 1 child = 1/33 + 1/82.5 + 1/132 = 0.0303 + 0.0121 + 0.0076 ≈ 0.05 work per day. Time = 1/0.05 = 20 days. Since 20 days is not among the options, the answer is 'None of these'.
