Explanation:

5/6 corresponds to 83.33%.

Hence, the amount that he kept with him corresponds to 100 − (83.33 + 5 + 10) = 1.67% of the total amount with him.
This corresponds to Rs. 850

Also, because he placed 10% in debentures and he got 10% interest, amount obtained in interest = 10% of 10% of amount with him
i.e. 1% of the amount with him.
∴ Interest earned = (850 x 1) /1.67
= 850 x 3/5 = 510
