DIRECTIONS for the following questions: These questions are based on the situation given below: A young girl Roopa leaves home with x flowers, goes to the bank of a nearby river. On the bank of the river, there are four places of worship, standing in a row. She dips all the x flowers into the river. The number of flowers doubles. Then she enters the first place of worship, offers y flowers to the deity. She dips the remaining flowers into the river, and again the number of flowers doubles. She goes to the second place of worship, offers y flowers to the deity. She dips the remaining flowers into the river, and again the number of flowers doubles. She goes to the third place of worship, offers y flowers to the deity. She dips the remaining flowers into the river, and again the number of flowers doubles. She goes to the fourth place of worship, offers y flowers to the deity. Now she is left with no flowers in hand.
The minimum number of flowers that could be offered to each deity is:
Number of flowers after the first dipping = 2x
Number of flowers after the second dipping = 2(2x-y) = 4x-2y
Number of flowers after the third dipping = 2(4x-2y-y) = 8x-6y
Number of flowers after the fourth dipping = 2(8x-6y-y) = 16x-14y
16x-14y = y
y = 16x/15
Minimum value of y = 16 when x = 15
