= $213.75 \approx 214$
=> Ans – (D)
2) Answer (A)
Expression : $(10008.99)^{2}/(10009.001)\times\sqrt{3589}\times0.4987=?$
$\approx \frac{(10009)^2}{10009} \times \sqrt{3600} \times 0.5$
= $1009 \times 60 \times 0.5$
= $1009 \times 30 = 30270$
$\approx 30,000$
=> Ans – (A)
3) Answer (E)
Expression : 399.9+ 206 x 11.009=?
$\approx 400 + (206 \times 11)$
= $400+2266 = 2666$
$\approx 2688$
=> Ans – (E)
4) Answer (A)
Expression : $\frac{2}{5}+\frac{7}{8}\times\frac{17}{19}\div\frac{6}{5}=?$
= $\frac{2}{5} + (\frac{7}{8} \times \frac{17}{19} \times \frac{5}{6})$
= $\frac{2}{5} + \frac{595}{912}$
$\approx 0.4+0.6=1$
=> Ans – (A)
