Unable to understand the solution Three cooks have to make 30 idlis They are known to make 20 pieces every minute working together. The first cook began working alone and made (20 pieces having worked for sometime more than three minutes. The remaining part of the work was done by the second and the third cook working together. It took a total of 8 minutes to complete the 80 idlis. How many minutes would it take the first cook alone to cook 160 idlis for a marriage party the next day?

Unable to understand the solution. Blank 2 does not suffice as a comparison between world peace and conflict and warfare has already been made. Blank 3 is interesting as numerous advantages have been listed out that have yet not been compared to any disadvantage. If we join the statements too it adds value to the whole paragraph.Kindly correct me if wrong Thankyou
