ANSWER: 104
Suppose,no of matches played with 70 average is x.
So, total runs = 70x
now adding 4 innings no of matches is (x+4)
after 4 innings average decreases to 70
So,total runs then will be 70(x+4)
So the equation is -> 72x + 80 = 70(x+4)
72x - 70x = 280 - 80 -> x = 100
total matches = 100 + 4 = 104
