### Quiz

1. $${6}^{3}$$× $${3}^{4}$$ ÷ $${9}^{3}$$ + $${?}^{2}$$ = $${7}^{2}$$

A. 4
B. 7
C. 5
D. 6

Explanation: $${6}^{3}$$× $${3}^{4}$$ ÷ $${9}^{3}$$ + $${?}^{2}$$ = $${7}^{2}$$
216 × 81 ÷ 729 + $${?}^{2}$$ = 49
216 × 81 × $$\frac{1}{729}$$ + $${?}^{2}$$ = 49
24 + $${?}^{2}$$ = 49
$${?}^{2}$$ = 49 – 24 = 25 = $${5}^{2}$$
∴ ? = 5

2. 70% of 1680 + ?% of 1750 = 55% of 2820 – 886

A. 36
B. 34
C. 28
D. None of these

Explanation: 70% of 1680 + ?% of 1750 = 55% of 2820 – 886
$$\frac{70}{100}$$ × 1680 + $$\frac{?}{10}$$× 1750 = $$\frac{55}{100}$$× 2820 – 886

1176 + $$\frac{?}{10}$$× 175 = 1551 – 886 = 665

$$\frac{?}{10}$$ × 175 = 665 – 1176 = –511
? = $$\frac{511 × 10}{175}$$ = –29.2

3. 326 × 14 – 12 × 88 + $${49}^{2}$$= ?

A. 5110
B. 5909
C. 5809
D. 6909

Explanation:

326 × 14 – 12 × 88 + $${49}^{2}$$= ?
4564 – 1056 + 2401 = 5909

4. 46% of 1250 + ?% of 4680 = 1183.4

A. 18
B. 15
C. 22
D. 13

Explanation: 46% of 1250 + ?% of 4680 = 1183.4

$$\frac{511 × 10}{175}$$× 1250 + $$\frac{?}{100}$$ × 4680 = 1183.4

575 + $$\frac{?}{5}$$× 234 = 1183.4

$$\frac{?}{5}$$× 234 = 1183.4 – 575 = 608.4
? = $$\frac{608.4 × 5}{234}$$ = $$\frac{3042}{234}$$ = 13

5. 8 $$\frac{1}{2}$$ + 4$$\frac{2}{7}$$ = 5$$\frac{1}{2}$$ + ?

A. 8 $$\frac{1}{7}$$
B. 6 $$\frac{1}{7}$$
C. 7 $$\frac{2}{7}$$
D. 5 $$\frac{1}{7}$$

Explanation: 8 $$\frac{1}{2}$$ + 4$$\frac{2}{7}$$ = 5$$\frac{1}{2}$$ + ?
? = 8 $$\frac{1}{2}$$ + 4$$\frac{2}{7}$$ – 5$$\frac{1}{2}$$
= (8 + 4 – 5) + $$\frac{1}{2}$$ +( $$\frac{2}{7}$$ – $$\frac{1}{2}$$)
7 + $$\frac{2}{7}$$ = 7$$\frac{2}{7}$$

1. 85% of 620 + x% of 480 = 70% of 890

A. 10%
B. 20%
C. 35%
D. 40%

Explanation: 85% of 620 + x% of 480 = 70% of 890

527 + x × 480 ÷ 100 = 623

x × 4.8 = 623 – 527

x × 4.8 = 96

x = 20%

2. (624 + 146) × 2 ÷ 77 = ? ÷ (– 2)

A. 40
B. – 30
C. 25
D. -40

Explanation: (624 + 146)×$$\frac{2}{27}$$ = $$\frac{?}{-2}$$
770 × $$\frac{2}{27}$$ = $$\frac{?}{-2}$$
20 × (– 2) = ?

? = – 40

3. (5.25 × 6 × 4) ÷ 7 – 2 = $${?}^{2}$$

A. 4
B. 6
C. 0
D. 2

Explanation: $$\frac{(5.25 × 6 × 4)}{7}$$ – 2 = $${?}^{2}$$
$$\frac{126}{7}$$– 2 = $${?}^{2}$$
18 – 2 = $${?}^{2}$$
$${?}^{2}$$ = 16
? = 4

4. 6$$\sqrt{6}$$ ×2$$\sqrt{3}$$ x 4$$\sqrt{2}$$÷ 12 = ? + 123 – 59

A. 75
B. 45
C. 80
D. None of these

Explanation: 6$$\sqrt{6}$$ ×2$$\sqrt{3}$$ x 4$$\sqrt{2}$$÷ 12 = ? + 123 – 59

? + 64 = 6$$\sqrt{6}$$ ×2$$\sqrt{3}$$ x 4$$\sqrt{2}$$÷ 12

? + 64 = $$\frac{(6 × 6 × 2 × 4)}{12}$$

? + 64 = 24

? = 24 – 64

? = – 40

5. [$$\sqrt{2401}$$ + $$\sqrt{625}$$– (29 + 5)]÷ 4 = $${?}^{1/2}$$

A. 125
B. 169
C. 144
D. 100

Explanation: 853 + $$\frac{(√2401 + √625) – (29 + 5)}{4}$$ = ? = 4990 – 9643 + 7750 = 3097 = $${?}^{1/2}$$
$$\frac{(49 + 25) – (34) }{4}$$ = $${?}^{1/2}$$
$$\frac{74-34}{4}$$ = $${?}^{1/2}$$

$$\frac{40}{4}$$ = $${?}^{1/2}$$
10 = $${?}^{1/2}$$
? = 100

1. 333.44 + 33.4444 + 3.444 + 3333.4 = ?

A. 3703.5284
B. 3704.7284
C. 3703.7284
D. 3703.7384

Explanation: 333.44 + 33.4444 + 3.444 + 3333.4 = ?

3 + 33 + 333 + 3333 + .4 + .44 + .444 + .4444 = ?

3 (1234) + 4(.4321) = ?

3702 + 1.7284 = ?

? = 3703.7284

2. 1 $$\frac{13}{6}$$ – 2 $$\frac{7}{18}$$ + 5 $$\frac{4}{9}$$ = ? + $$\frac{7}{3}$$

A. 2$$\frac{3}{4}$$
B. 5$$\frac{2}{3}$$
C. 3$$\frac{8}{9}$$
D. 1$$\frac{3}{4}$$

Explanation: 1 $$\frac{13}{6}$$ – 2 $$\frac{7}{18}$$ + 5 $$\frac{4}{9}$$ = ? + $$\frac{7}{3}$$
1 $$\frac{13}{6}$$ – 2 $$\frac{7}{18}$$ + 5 $$\frac{4}{9}$$ – $$\frac{7}{3}$$ = ?

1 – 2 + 5 + ($$\frac{13}{6}$$ – $$\frac{7}{18}$$ + $$\frac{4}{9}$$ – $$\frac{4}{9}$$)
6 – 2 + $$\frac{39 – 7 + 8 – 42}{18}$$ = ?
4 + $$\frac{-2}{18}$$ = ?
3 + (1 – $$\frac{1}{9}$$ = ?

? = 3 + $$\frac{8}{9}$$
? = 3$$\frac{8}{9}$$

3. $${?}^{2}$$ – 18.75 – 11.25 = 9.09% of 396 + 295

A. 30
B. 25
C. 21
D. 19

Explanation:$${?}^{2}$$ – 18.75 – 11.25 = 9.09% of 396 + 295

$${?}^{2}$$ – 30 = 396 ÷ 11 + 295

$${?}^{2}$$ = 36 + 295 + 30

$${?}^{2}$$ = 361

? = 19

4. (37.5% of 1160) ÷( $$\sqrt{441}$$ – $$\sqrt{256}$$ ) = ? + 23

A. 70
B. 55
C. 61
D. 64

Explanation: $$\frac{37.5% of 1160}{441 – 256}$$ = ? + 23

$$\frac{\frac{3}{8}×1160}{{21 – 16}}$$ = ? + 23
$$\frac{435}{5}$$ = ? + 23
87 – 23 = ?

? = 64

5. (11.275 + 101.237 + 13.5) ÷ $$\sqrt[3]{64}$$(17.657 + 18.976) ÷ $${2}^{2}$$ = $${?}^{2}$$ + 8.379 ÷ 4

A. 3
B. 5.5
C. 4.5
D. 6

Explanation:(11.275 + 101.237 + 13.5) ÷ 64 – (17.657 + 18.976) ÷ 22 = $${?}^{2}$$ + 8.379 ÷ 4

(126.012) ÷ 4 – (36.633) ÷ 4 = $${?}^{2}$$ + 8.379 ÷ 4

(126.012) ÷ 4 – (36.633) ÷ 4 – (8.379) ÷ 4 = $${?}^{2}$$

(126.012 – 45.012) ÷ 4 = ?2

$${?}^{2}$$ = 81 ÷ 4

? = $$\frac{9}{2}$$ = 4.5
