Given: The income of Amala is 180% of Balu and the income of Charu is 150% of the income of Amala. Total income of Amala, balu and Charu is Rs. 1,10,000. Now, If we assume that the income of Balu is x, then- Income of Amala is 180% of x i.e. 1.8x Similarly, income of Charu will be 150% of 1.8x i.e 1.5 × (1.8x) = 2.7x Now, the Total income of Amala, Balu, and Charu will be as ⇒ x + 1.8x + 2.7x = 110000 ⇒ 5.5x = 110000 ⇒ x = 110000 ÷ 5.5 = 20000 Rs. Now, Charu's income, after putting the value of x is equal to 2.7 × 20000 = 54000 Rs. Hence, the correct answer is "Option (4)".
