To solve for the World Bank index
for yen yesterday we should first look at Yen’s current standing. So today the
World Bank Index of yen is 0.38 and the constant World Bank Index is 0.40 with
-0.03 a day. So for today’s index we have 0.38/0.40=0.95. To compare it with
yesterday’s x/0.43=0.95. Which will give us the answer that x=0.4085 or 0.41.
