Correct Answer - Option 1 : 60
Given:
On a certain match between India and Pakistan, India has a success rate of 60% against Pakistan in all ODIs played between two countries. They lost next 40 ODIs in a row to Pakistan and their success rate comes down to 20%.
Concept used:
Percentage
Calculation:
Let the number of matches be x
Matches won = 60% = \(\frac{3}{5}x\)
Number of matches Lost = 40
Total matches = x + 40
Success rate = Matches won / Total matches
⇒ \(\frac{{\frac{3}{5}x}}{{x + 40}} = \frac{{20}}{{100}}\)
⇒ x = 20
Total matches = 20 + 40 = 60
