Answer:
83,900
Explanation:
100/33560 = 250/x
There are 2 options to solve. You can cross multiply:
100x = 33560*250
100x = 8,390,000 Divide by 100
x = 83,900
I also see that you start with 100 naira and want to see the value at 250 naira.
250 is 2.5 times 100. If you take the original 33560 fr and multiply that by 2.5, you will get 83,900.
