- 25
- 200
- 30
- 300
Hint:

The correct answer is: 30
Here, it is given that the ratio of blueberries and strawberries is 1:7. There are 210 strawberries. We have to find the number of blueberries.
Let the number of blueberries be x and number of strawberries be 7x.
Then, 7x = 210.
=> x = 210/7
=> x = 30.
So, number of blueberries = x = 30.
Hence, the correct option is C.
We can also find the number of blueberries by dividing the number of strawberries by 7.
