A shop sells two sizes of coffee: small and large. The ratio of the amount of coffee in the small cup to the amount of coffee in the large cup is 2:5. The small cup holds 100ml. How much coffee does the large cup hold?
200 ml
250 ml
300 ml
500 ml
Explanation
Since 2 parts = 100ml, 1 part = 50ml, So 5 parts = 5*50ml = 250ml.
