Answer 1

Answer:

18000

Step-by-step explanation:

Suppose you have 100 rs

at the end of 1st year - loss = 10%

remaining amount  = 100-100*10%

                                 =90

from question,

2nd year he gains 20% of the remaing amount= 90+90*20%

                                                                              = 108

from question profit = 1440rs

hence, 108-100= 1440rs

      => 8= 1440 rs

     => 1 = 180 rs

hence => original capital we take = 100

hence original  capital = 100*180=18000 Rs Ans.
