Solution:Given, 7451, 3254, 7353, 3464, 1958
By applying the condition as per question we get, 5471, 5234, 5373, 6434, 5918 Now arranging the above series in descending order
we get, 6434, 5918, 5471, 5373, 5234 Hence, there is no such number in the above arrangement which place remains the same. so the answer is zero
