ATQ, Let the income of ‘Bhishma’ be Rs.'b' For I: Income of ‘Amit’ = Rs. 1.25b Or, 1.25b = 20000 Or, b = 16000 Average income of ‘Amit’ and ‘Bhishma’ = (b + 1.25b)/2 = (20000 + 16000)/2 = Rs.18000 Therefore, I is true. For II: Income of ‘Amit’ = Rs. 1.6b Or. 1.6b = 20000 Or, b = 12500 Average income of ‘Amit’ and ‘Bhishma’ = (b + 1.6b)/2 = (20000 + 12500)/2 = Rs. 16250 Therefore, II is true. For III: Income of ‘Amit’ = Rs. 3.2b Or. 3.2b = 20000 Or, b = 6250 Average income of ‘Amit’ and ‘Bhishma’ = (b + 3.2b)/2 = (20000 + 6250)/2 = Rs.13125 Therefore, III is false.
