- According to options lets check for the increase in flowers....
when he plucks 7 flowers next day 37 more flowers grow.
terefore a total increase of 30 flowers are there (37-7).
now adding 30 flowers in 189 we get=219.
next day adding another 30 flowers we get =249.
so the option (b) 249 is the correct answer. - 11 years agoHelpfull: Yes(39) No(1)
- ans 249
simply find out the difference between the roses plucked and bloom for each day.
it would be(37-7),(36-6),(9-24),(18-23)
implies 30,30,-15,-5
- indicates that no of roses decrease by that no.
initially no of roses=189
after 1 day roses= 189+30=219
on second day=219+30=249... we stop here as the option matches - 11 years agoHelpfull: Yes(14) No(2)
- 249
as per the situation - 11 years agoHelpfull: Yes(3) No(0)
- The possibilities can be that 30 roses increase per day or, 15 or 5 roses decrease per day (by subtracting the no.of roses plucked & number of roses grown per day). So, the unit place number can be 0 or 5 different from the unit place of initial no. of roses i.e., it can be 9 or 4. Thus, the only answer matching is (b) 249.
