Question 136

What is the least number that can be added to 5300 to make it a perfect square?

Solution

In this question , we should have a better understanding of squares.

Here we know that 70 x 70 = 4900 So in order to reach near about 5300 , we must look at squares of numbers near 70 like 71, 72 , 73

73 x 73 =5329

As we can see that 73 x 73 is the nearest perfect square which require addition of only 29 to make 5300 a perfect square

Hence option C is correct
