Correct Answer - B
Let the number of matches played be 60+ x .This is minimum when x is minimum.
As the target was achieved for the minimum value of x all the x matches must have been won.
Let the minimum (x) =y
`:. ` The total number of matches won `=(30)/(100) (60)+y =18 +y`
` (18+y)/(60+y) lt (100)% =44%`
`1800+ 100y =2640+ 44y`
56y=840
y=15
