No. of pastries made by Tulika in 1 min = 29/60
by Prachi = 3/10
by Priyanka = 7/20
Let the time taken by them to make 204 pastries be 'x' mins
When they work together
x (29/60 + 3/10 + 7/20) = 204
x ( 68/60 ) = 204. ( Taking 60 as LCM )
x = 204 * 60/68 = 180 minutes
Time taken by the three to make 204 pastries is 180 minutes = 3 hours
