Step by step explanation:-
Given
price of 4 kg of rice is equal to the price of 9 kg of wheat.
price of 1 kg of wheat is Rs 20
To find
what is the total cost of 8 kg of rice and 9 kg of wheat?
Solution
Price of 1 kg of wheat = 20
So, Price of 9 kg of wheat = 20*9= Rs 180
and,
Price of 4kg of rice = 9kg of wheat (Given)
4 kg of rice = 180
price of 1 kg of rice = 180\4 = Rs 45
Now, we can easily find ,
Cost of 8 kg of rice= 8*45=360
Cost of 9 kg of wheat = 9*20=180
Therefore , total cost of 8kg of rice and 9kg of wheat is Rs 540
