Eshan and Mary each wrote two or three poem every day over a period of time eshan wrote 43 poems while Mary wrote 61. The number of days in this period is.....

a) 19
b) 21
c) 20
d) 18

• ans: b)21
  suppose, Eshan writes 2poems in first 18days 18*2=36.
  2poems in next 2 days 2*2=4, 36+4=40
  and 3poems in next 1day 1*3=3, 40+3=43
  So, Ultimately he takes (18+2+1) = 21days to write 43 poems.
  
  now suppose, Marry writes 3poems in 1st 18days 18*3=54
  2poems in next 2days 2*2=4, 54+4=58
  3poems in next 1 day 1*3=3, 58+3=61
  So ultimately marry takes (18+2+1)= 21days to write 61poems.

  let no of days be x
  Mary wrote 61 poems in x days (maximum of 3 poems per day)
  Therefore x is greater than 20(3*20

• each can write max 3 Poems a day..so let Eshan writing 2 Poems each day which make 2*20=40 and one day he can write 3 Poems.that makes 21 days.
  similarly,let Mary write 3 Poems each day.therefore,3*20=60 and one day she write 1 Poem.that makes 21 days.
  hence,(b)

• ans 21
  eshan wrote 2 poems each day for 20 days ==20*2=40,and 3 poems in one day 3*1=3.
  ==>20*2+1*3=43 ==>21days
  mary wrote 3 poems each day for 19 days ==19*3=57,and 4 poems in 2 days.
  ==>19*3+2*2 ==>19+2=21 days

• total no of poems they wrote ...43 + 61 =104.
  total no of poems ther wrote in 1 day = around 5
  
  104/5 = 20.80 or 21

• 10 years agoHelpfull: Yes(1) No(11)
• total poems are 105.so every 3 or 2 poems are wrote.
  so based on option ans is 21
  (21*2)+(21*3)=105
• 10 years agoHelpfull: Yes(1) No(1)
• ans is b
  since 43/3 is not there
  43/2~21
  and
  61/3~21 61/2 not there
  so ans is 21

• Ans is b)21..
  because eshan and mary can write max upto 3 poems a day...
  eshan wrote 61 poems...21 * 3=63...eshan wrote 3 poems for about 19 days and 2 poems for about 2 days which gives 19*3 + 2*2=57+4=61..
  so answer is 21..
