To calculate the water rate in 1975, we need to find 20% of 2 naira 50 kobo and add it to the original amount.
First, let's convert 2 naira 50 kobo to kobo.
1 naira = 100 kobo
So, 2 naira = 2 * 100 kobo = 200 kobo
Thus, 2 naira 50 kobo is equal to 200 kobo + 50 kobo = 250 kobo.
Next, we need to find 20% of 250 kobo.
20% = 20/100 = 0.20
20% of 250 kobo = 0.20 * 250 kobo = 50 kobo
Finally, we add the 20% increase to the original water rate:
250 kobo + 50 kobo = 300 kobo
Therefore, Ola paid 300 kobo as water rate in 1975.

Thus, 2 naira 50 kobo is equal to 200 kobo + 50 kobo = 250 kobo.
Next, we need to find 20% of 250 kobo.
20% = 20/100 = 0.20
20% of 250 kobo = 0.20 * 250 kobo = 50 kobo
Finally, we add the 20% increase to the original water rate:
250 kobo + 50 kobo = 300 kobo
Therefore, Ola paid 300 kobo as water rate in 1975.
