We can use the alligation method or the weighted average method taking 40% and 100% as two values and 50% as the result so we get weight ratio of old to new matches to be 50:10 hence 50 matches.
@@moneytalks-real You can solve this using Alligations - since the concept being used here is weighted averages. One way to think of this problem is to trick your brain into recognising that the logic given in the problem is not too different from your normal Milk and water questions dealing with concentrations. Give it a try. Hint here is to recognise that you can treat 40% matches won out of some 'x' matches. Next sentence gives you 'n' matches,100% of these 'n' matches were won. You can 'mix' these values to get 50% winning percentage and therefore the ratio of x:n . Further sentences give you the actual value of further matches played (15) and the win rate (again 100%). Give it a try if you followed so far. Your Alligation basics and concepts should be strong before you can apply it to problems that are not strictly dealing with milk, water and solutions.
Good one🎉

You can solve this question in 45-60 seconds by using Alligations, its not that lengthy. CAT has also asked similar questions in the past.
can you elaborate?

Total matches are asked so answer should be 60 nn !?
shouldn't we add 15 also because its total matches
And add 10 also... because they also played n matches.
I think answer should be 75
N=10, x=50 so total matches played would be 50+10+15=75
Why are people talkig about alligations while I think we can easily solve the question using just the options ?
bro try not using options in ques having CBD or NOTA
