Arun's income is 150% of Bala's income. Income of Chandru is 120% of the income of Arun. If the total income of Arun, Bala and Chandru is Rs.86000, then what is the income of Chandru?

Correct option is A

Let say, Bala's income=b.
So, Arun's income=1.5b
And Chandra's income-1.2x1.5b=1.8b.
So,(1.5b+b+1.8b)=86000.
or, 4.3b=86000.
or, b=20,000.
Chandru's income=1.8×20,000=36000.
