Now she offers y flowers to the first deity & dips the remaining flowers in the river so that they get doubled again. She offers y flowers to the second deity as well & repeats the same process for 3rd & 4th deity. After offering flowers to the 4th deity, she realises that she is left with no flowers at all.
Explanatory Answer
Method of solving this CAT DILR Question from Analytical Reasoning question
Sandhya starts with the even number of flowers because after last offering, she is left with no flowers and the flower have been doubled, it has to be in even numbers.
So, she offered 32 flowers at each deity. It can also be inferred that the number of flowers offered is actually a power of 2, because each time the flowers are getting doubled. So the minimum number of flowers that she can start with is 15 and the minimum number she can offered is 16.
