(c) 698
The certain amount amounts to rupees 815 in three years and to eight hundred fifty four in four years therefor the amount increment in an year will be equal to 854-815= Rs 39/-
Now for three years the amount increment will be 39*3=Rs 117

Now by subtracting 117 from eight hundred fifteen we get Rs 698
which is the required answer.
