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 %
