Let x be the value of the unknown number.

x= $\frac{9876}{24.96}$ + 215.005 – 309.99

= 395.67 – 94.985 $= \approx$ 300

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.

Let x be the value of the unknown number.

x= $\frac{9876}{24.96}$ + 215.005 – 309.99

= 395.67 – 94.985 $= \approx$ 300

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, $X = \frac{29.38 \times 37.05}{93.05} = 11.69 \approx 12$

21 + 4 x 3 + 9
= 42

22.9889 + 0.002 ÷ 1
= 22.9889 + 0.002
= 22.9891 ≈ 23

5+10 = 15 (5.26% = 1/19 and 5.88%= 1/17)

40+10 = 50 (7.14% = 1/14)

100+10 = 110 (16.66% = 1/6 and 9.09% = 1/11)

10+10 = 20 (11.11% = 1/9 and 8.33% = 1/12)

5+10 = 15 (5.88% = 1/17 )

8+10 = 18 (12.5% = 1/8 and 11.11% = 1/9)

As we can see that 33.33% of 150 will be $\frac{1}{3}$ of 150 i.e. 50 and 66.66% of 180 will be $\frac{2}{3}$ of 180 i.e. 120
