Answers & Solutions:

1) Answer (A)

Expression : 415.9 ÷ 4.02 + 13.04 x 28.978 = ?

= $(\frac{416}{4})+(13\times 29)$

= $104+377=481$

$\approx 480$

2) Answer (D)

Expression : ? % of (767 ÷ 6) = 7.889²

=> $x\mathrm{\%}$ of $\frac{768}{6}=(8{)}^2$

=> $\frac{x}{100}\times 128=64$

=> $x=64\times \frac{100}{128}$

=> $x=\frac{100}{2}=50$

3) Answer (C)

Expression : 319.89 – 15.03 x 3.692 = 1039.88 ÷ ?

=> $320–(15\times 4)=\frac{1040}{x}$

=> $320–60=\frac{1040}{x}$

=> $x=\frac{1040}{260}=4$

4) Answer (C)

Expression : 124.99 x 4.998 + 129.992 – 75.05 = ?

$\approx (125\times 5)+130–75$

= $625+55=680$

5) Answer (C)

Expression : $\sqrt{239.92\times 2.995–94.95}$ = ?

$\approx \sqrt{(240\times 3)–95}$

= $\sqrt{720–95}=\sqrt{625}$

= $25$

6) Answer (E)

Expression : $\sqrt[3]{1331}$

= $\sqrt[3]{11\times 11\times 11}$

= $11$

7) Answer (B)

Expression : 18.5% of 220 + 12.4% of 680 = ?

= $(\frac{18.5}{100}\times 220)+(\frac{12.4}{100}\times 680)$

= $40.7+84.32=125.02$

8) Answer (C)

Expression : 188.21 – 27.54 – 11.93 = ?

= 188.21 – 39.47

= 148.74

9) Answer (D)

Expression : 1268 ÷ 8 ÷ 2 = ?

= $\frac{1268}{8}÷2$

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

10) Answer (E)

Expression : $8^{1.1}\times {4^2}^{.7}\times 2^{3.3}=2^{?}$

=> $(2{)}^{3\times 1.1}\times (2{)}^{2\times 0.7}\times (2{)}^{3.3}=(2{)}^x$

=> $(2{)}^{3.3}\times (2{)}^{1.4}\times (2{)}^{3.3}=(2{)}^x$

=> $(2{)}^{3.3+1.4+3.3}=(2{)}^x$

Comparing both sides, we get :

=> $x=3.3+1.4+3.3=8$

11) Answer (C)

Expression : $\sqrt{?}$  x 479.87 ÷ 12.01 = 179 + 139.99

=> $(\sqrt{x})\times \frac{480}{12}=180+140$

=> $\sqrt{x}\times 40=320$

=> $\sqrt{x}=\frac{320}{40}=8$

=> $x=(8{)}^2=64$

12) Answer (C)

Expression : 629 ÷ 9.02 – 139.996 ÷ 7.06 = ?

= $(\frac{630}{9})–(\frac{140}{7})$

= $70–20=50$

13) Answer (A)

Expression : 719.999 ÷ 12.0001 + 12.9999 x 2.999 + 1.0001 = ?²

=> $\frac{720}{12}+(13\times 3)+1=(x{)}^2$

=> $60+39+1=100=(x{)}^2$

=> $x=\sqrt{100}=10$

14) Answer (D)

Expression : 45% of 401 ÷ 3 – ? = 6.022

=> $45\mathrm{\%}$ of $400÷3–x=6$

=> $\frac{45}{100}\times 400÷3=6+x$

=> $\frac{45\times 4}{3}=6+x$

=> $x+6=15\times 4=60$

=> $x=60–6=54$

15) Answer (B)

Expression : 13.999% of 134.999 + $\sqrt{7.999\times 8.0001}$  = 20 % of ?

$\approx 14\mathrm{\%}$ of $135+\sqrt{8\times 8}=\frac{20}{100}\times x$

=> $18.9+8=\frac{x}{5}$

=> $x\approx 5\times (19+8)=5\times 27$

=> $x=135$
