1. $$2197 \div 21.05 + \frac{2}{3} \times 4224 - 15.5 = ?$$

1. 2905
2. 2824
3. 2566
4. 2422

Solution: $$= 2197 \div 21.05 + \frac{2}{3} \times 4224 - 15.5$$ $$= 2197 \div 21 + \frac{2}{3} \times 4224 - 15.5$$ $$= 104.6 + 2816 - 15.5$$ $$= 2905.1 \approx 2905$$

1. $$1429 - 4.71 \times 25.5 - ?^2 = 1250$$

1. 6
2. 8
3. 9
4. 12

Solution: $$1429 - 4.71 \times 25.5 - ?^2 = 1250$$ $$1429 - 5 \times 25 - ?^2 = 1250$$ $$1429 - 125 - ?^2 = 1250$$ $$1429 - 125 - 1250 = ?^2$$ $$54 = ?^2$$ $$\sqrt{54} = ?$$ $$8 \approx ?$$

1. $$1825 \div 35.2 + 25.11 \times \sqrt{365} = ?$$

1. 205
2. 306
3. 450
4. 502

Solution: $$= 1825 \div 35.2 + 25.11 \times \sqrt{365}$$ $$= 1825 \div 35 + 25 \times \sqrt{365}$$ $$= 52.14 + 25 \times 18$$ $$= 52 + 450 = 502$$

1. $$?$$ + 25.2% of 545 $$\div$$ 16.8% of 149.78 = 210

1. 205
2. 302
3. 406
4. 502

Solution: $$? + 25.2% of 545 \div 16.8% of 149.78 = 210$$ $$? + 25% of 545 \div 17% of 150 = 210$$ $$? + \frac{25 \times 545}{100} \div \frac{17 \times 150}{100} = 210$$ $$? + 136.25 \div 25.5 = 210$$ $$? + 136 \div 25 = 210$$ $$? + 5.44 = 210$$ $$? = 204.56 \approx 205$$

1. $$4232 \div 15.98 - 2126 \div 18.97 = ?$$

1. 126
2. 153
3. 162
4. 178

Solution: $$= 4232 \div 15.98 - 2126 \div 18.97$$ $$= 4232 \div 16 - 2126 \div 19$$ $$= 264.5 - 111.89$$ $$= 265 - 112 = 153$$

1. $$2 \frac{3}{5} \times 4 \frac{5}{3} \times 3 \frac{6}{7} = ?$$

1. 72
2. 82
3. 92
4. 98

Solution: $$= 2 \frac{3}{5} \times 4 \frac{5}{3} \times 3 \frac{6}{7}$$ $$= \frac{13}{5} \times \frac{17}{3} \times \frac{27}{7}$$ $$= 2.6 \times 5.6 \times 3.84$$ $$= 3 \times 6 \times 4$$ $$= 72$$

1. $$4225 \div 25 \div 5 = ?$$

1. 26
2. 34
3. 42
4. 53

Solution: $$= 4225 \div 25 \div 5$$ $$= \frac{4225}{25 \times 5}$$ $$= 33.8 \approx 34$$

1. 12.05% of 444 $$\div$$ (22.2% of 152.8) + ? = 112

1. 133
2. 120
3. 110
4. 102

Solution: 12% of 444 $$\div$$ (22% of 153) + ? = 112 $$53.28 \div 33.66 + ? = 112$$ $$53 \div 34 + ? = 112$$ $$1.56 + ? = 112$$ $$? = 112 - 1.56$$ $$= 110.44 \approx 110$$

1. 1533.10 - 15.02 $$\times$$ 12.94 + $$?^2$$ = 1456

1. 22
2. 18
3. 15
4. 11

Solution: $$1533 - 15 \times 13 + ?^2 = 1456$$ $$1533 - 195 + ?^2 = 1456$$ $$?^2 = 118$$ $$? = \sqrt{118}$$ $$? \approx 11$$

1. 1568 $$\div$$ 26.94 + 22.02 $$\times \sqrt{577}$$ = ?

1. 532
