ExpressionÂ :Â 42×21-12 ?=880

L.H.S. =Â 42×21-12 ? = 882 – 12 ?

(A) :Â A

= $882 – 12 \div 3 = 882-4=878$

(B)Â :Â F

= $882-12 \times 2 = 882-24=858$

(C) : G

= $882-12 – 2 = 882-14=868$

(D) : D

= $882-12 +3 = 882-9=873$

=> Ans – (E)

ExpressionÂ :Â 36+12 ? =48

L.H.S. =Â 36+12 ?

(A) :Â A followed by F

= $36+12 \div 3 \times 2 = 36+ \frac{12}{3} \times 2$

= $36+8=44$

(B) :Â A followed by B

= $36+12 \div 3 \times 3 = 36+12=48$ = R.H.S.

=> Ans – (B)

ExpressionÂ :Â 48? +12×4=80

L.H.S. =Â 48? +12×4 = 48Â ? + 48

(A) :Â E followed by B

=Â $48 \div 3 \times 2 + 48$

= $32+48=80$ = R.H.S.

=> Ans – (A)

ExpressionÂ :Â 18×3 Ã·2+3 <27 ?

L.H.S =Â 18×3 Ã·2+3

= $\frac{54}{2}+3 = 30$

Now, R.H.S. should be greater than 30

R.H.S. =Â 27 ?

(A) :Â D followed by A

= $27+3 \div 3 = 27+1=28$

(B) :Â A followed by G

= $27 \div 3-2 = 9-2=7$

(C) :Â D followed by G

= $27+3-2=28$

(D) :Â D followed by H

=Â $27+3+2=32$

=> Ans – (D)

ExpressionÂ :Â (48+9)Ã·19×2=12 ?

L.H.S. =Â (48+9)Ã·19×2

= $\frac{57}{19} \times 2 = 6$

R.H.S. =Â 12 ?

(A) :Â A followed by H

= $12 \div 3+2 = 4+2=6$

=> Ans – (A)

ExpressionÂ :Â $\frac{2}{5}+\frac{7}{8}\times\frac{17}{19}\div\frac{6}{5}=?$

= $\frac{2}{5} + (\frac{7}{8} \times \frac{17}{19} \times \frac{5}{6})$

= $\frac{2}{5} + \frac{595}{912}$

$\approx 0.4+0.6=1$

=> Ans – (A)

ExpressionÂ :Â 399.9+ 206 x 11.009=?

$\approx 400 + (206 \times 11)$

= $400+2266 = 2666$

$\approx 2688$

=> Ans – (E)

ExpressionÂ :Â $(10008.99)^{2}/(10009.001)\times\sqrt{3589}\times0.4987=?$

$\approx \frac{(10009)^2}{10009} \times \sqrt{3600} \times 0.5$

= $1009 \times 60 \times 0.5$

= $1009 \times 30 = 30270$

$\approx 30,000$

=> Ans – (A)

ExpressionÂ :Â $\sqrt{45689}=?$

= $\sqrt{7 \times 61 \times 107}$

= $213.75 \approx 214$

=> Ans – (D)

ExpressionÂ :Â 3/5 of 7/19 of 5/28 of 243 = ?

= $\frac{3}{5} \times \frac{7}{19} \times \frac{5}{28} \times 243$

= $\frac{3}{19 \times 4} \times 243$

= $\frac{729}{76} \approx 10$

ExpressionÂ :Â $12.95\times7.05+(85.01)^{2}\times10.99=?$

= $(13 \times 7) + (85^2 \times 11)$

= $91 + (7225 \times 11)$

= $91 + 79475 = 79566$

ExpressionÂ :Â 432.62 – 269.21 $\div$(11.9 % of 78) =?

= $432 – (270 \times \frac{1}{\frac{12}{100} \times 78})$

= $432 – (270 \times \frac{100}{936})$

= $432 – 29 = 403$

$\approx 400$

ExpressionÂ :Â 899.99$\div$ 45.072 = ? – 224.488

=> $\frac{900}{45} = x – 224$

=> $20 = x – 224$

=> $x = 224 + 20 = 244$

ExpressionÂ :Â 1268 Ã· 8 Ã· 2 = ?

= $\frac{1268}{8} \div 2$

= $\frac{158.5}{2} = 79.25$

Expression : ${8^{1.1}} \times {4^2}^{.7} \times {2^{3.3}} = {2^?}$
=> $(2)^{3 \times 1.1} \times (2)^{2 \times 0.7} \times (2)^{3.3} = (2)^x$
=> $(2)^{3.3} \times (2)^{1.4} \times (2)^{3.3} = (2)^x$
=> $(2)^{3.3 + 1.4 + 3.3} = (2)^x$
=> $x = 3.3 + 1.4 + 3.3 = 8$
