• ans-4
  roses are decreasing so only pair we can use are 24,9 or 23,18
  24-9=15 , 189mod15=9 (that's not a option)
  23-18=5 , 189mod5=4 ans.

• As given, on monday 189 roses are present.
  7 or 6 or 24 or 23 are plucked on consecutive days and 37 or 36 or 9 or 18 roses are newly bloomed.
  let for 'x' days roses are plucked then x-1 days roses are bloomed.
  finally roses left are 189-24(x)+9(x-1)=180-15x = 30(for x=10)

• sorry initial answer was not correct.
  only two of the options taken 24-9 23-9 because in answ9ers flowers are less.
  if 23 taken 189-23=166 if add 18 then 184 then 184-23 then add 18=174 if we obserb unit place when pluck 23 and add always it was 4... so finally we have 4 flowers

• 37 is the answer, assume that initially there are 7 flowers in the garden. then next day the garden will have 37 flowers

• if the optins are 26,24,249,232 then the answer can be 249....
  it is like 189-24x+36(x-1)=153+12x=249 for x=8

• Little bit tricky,
  CASE I
  If he plucks 24 flowers and 9 comes:- In this case flowers decreases day by day as 1st day there is a loss of 15 flowers and then next day again there is a loss of 15 flowers and it is go on until we reach flower
  
  CASE II
  If he plucks 23 flowers and 18 comes:- In this case also flowers decreases day by day and never reach upto 189.
  
  CASE III
  If he plucks 7 flower and 37 comes:- Now, there is a gain in flowers each day
  CASE IV
  Here also there is a gain in each day
  
  So as per option if there is 189 flowers on Monday and there maybe either 4 or 37 or 7 or 30 flowes left then definitely there is a loss in flower in each day and therefore, ans was demonstrated by either CASE 1 or CASE 2
  
  Solving CASE 1,
  There is a loss of 15 flowers each day.
  After 12 days he lose 180 flowers and only 9 left.
  
  Solving CASE 2, there is a loss of 5 flowers each day.
  After 37 day, he lose 185 flowers and only 4 left
  9 is not in option so answer is 4
