Correct Answer: 7254
Solution :
Given:
53 – 34 = 5334 and 65 – 46 = 6456
Like, 53 – 34 = 5334→
On combining 53 – 34, we get 5334.
Now, on interchanging the position of the second and the third digits of 5334, we get 5334.
And, 65 – 46 = 6456→
On combining 65 – 46, we get 6546.
Now, on interchanging the position of the second and the third digits of 6546, we get 6456.
Similarly, follow the same pattern for 75 – 24→
On combining 75 – 24, we get 7524.
Now, on interchanging the position of the second and the third digits of 7524, we get 7254.
Therefore, the required missing number is 7254. Hence, the fourth option is correct.
