Nirav and Siddharth borrowed a tractor for 23 days. Nirav ploughed 12 acres per day for a certain number of days and then Siddharth used it to plough 15 acres per day for the remaining days. If they paid RS.3,000 and RS.2,000 respectively, for how many days did Nirav use the tractor? Assume that they share the total rent in proportion to the land that they plough
a)12 b) 15 c) 8 d) 16

• If Nirav used tractor for x days, then
  
  12x/(15(23-x) = 3/2
  
  solving it,
  x=15
  
  so nirav used tractor for 15 days.

• i just verify the options if n=15days then s=8 days therefore we have 12*15:15*8=12:8=3:2 money paid in ratio 3:2 so b is the answer

• let neerav use tractor for x days
  so,as per the question 12x/[15(23-x)]
  on solving the above equation
  x=15
  therefore neerav used the tractor for 15 days
