Then, from the questions, given that Rani ate 2/7 part of a cake = 1 – (2/7) = (7 – 2)/7 = 5/7 So, Ravi ate 4/5 of the remaining cake = (4/5) × (5/7) = 4/7 Therefore, the part of the cake left = (5/7) – (4/7) = 1/7Read more on Sarthaks.com - https://www.sarthaks.com/786899/rani-ate-part-of-a-cake-while-her-brother-ravi-ate-4-5-of-the-remaining-part-of-the-cake-left-is
