Answer:

A = 5 %

Step-by-step explanation:

आय   =  100M

आयकर  =  A %

आयकर  =  (A/100)100M = AM

नेट आय =  100M - AM

आयकर 19% बढ़ जाए = A + (19/100)A = 1.19A

आयकर = 1.19AM

नेट आय = 100M - 1.19AM

नेट आय 1% कम

(100M - AM)(1 - 1/100) = 100M - 1.19AM

=>(100M - AM)(0.99) = 100M - 1.19AM

=> 99M - 0.99AM = 100M - 1.19AM

=> 0.2AM = M

=> 0.2A = 1

=> A = 5 %
