Question 5: What is the least number that can be added to 5300 to make it a perfect square?

a) 25
b) 33
c) 29
d) 36
e) None of these

Question 6:
46% of a number is 115. What is 150% of that number ?

a) 370
b) 385
c) 365
d) 360
e) None of these

Let the number to come in place of the question mark be equal to $X$

So, $29.38 \times 37.05 \div X + 7.45 = 100.5$
Or, $29.38 \times 37.05 \div X = 93.05$
So, $X = \frac{29.38 \times 37.05}{93.05} = 11.69 \approx 12$

Let the number to replace the question mark be equal to $X$

Hence, $695.95\div 29.07 \times X + 40.25 = 399.99$

$399.99 \approx 400$ and $695.95 \approx 696$ and $29.07 \approx 29$

So, the expression looks like $696 \div 29 \times X + 40 = 400$
Hence, $24 \times X = 360$ or $X = 15$

Since an approximate answer is sufficient, you can rewrite the question as $10000 \div 50 \times 5^{2} – 1130$

Following BDMAS rule the result is 3870.

The nearest value is 3800.

Hence Option A is the correct answer.

46813 + 32298 – 13234 – 31112
79111-44346
=34765

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

So, $\frac{46}{100}\times{y} = 115$
150% of 250 = $\frac{150}{100}\times250 = 375$
