1
7(6 - ?) × 119 ÷ 1225 = 289 × 20.98 × 7.03 ÷ 3.02 ÷ 4.95
» Explain it
A
7(6 - ?) × 119 ÷ 1225 = 289 × 20.98 × 7.03 ÷ 3.02 ÷ 4.95

7(6 - ?) × 119 ÷ 35 = 17 × 21 × 7 ÷ 3 ÷ 5

7(6 - ?) = 17 × 21 × 7 ÷ 3 ÷ 5 ÷ 119 × 35

7(6 - ?) = 7 × 7

7(6 - ?) = 72

6 - ? = 2

? = 6 - 2 = 4

Hence, option A is correct.
2
(128.78 + 307.24 + 111.8) – (246.35 – 786.47) = ?2
» Explain it
A
(128.78 + 307.24 + 111.8) – (246.35 – 786.47) = ?2

(129 + 307 + 112) – (246 – 786) = ?2

548 – (– 540) = ?2

?2 = 548 + 540

?2 = 1088 ≈ 1089

? = 33

Hence, option A is correct.

3
54.7% of 1190 ÷ (676 + 1728.11361) = ?2 ÷ 57.02
» Explain it
C
54.7% of 1190 ÷ (676 + 1728.11361) = ?2 ÷ 57.02

1190 × 55/ 100 ÷ (26 + 12 – 19) = ?2 ÷ 57

654.5 ÷ 19 = ?2 ÷ 57

655 ÷ 19 × 57 = ?2

?2  = 655 × 3 = 1965

? = 44.32 ≈ 44

Hence, option C is correct.
4
 7 9 % of 208 + (16.9 × 304) = ?1/2 + 125 13 323
» Explain it
B
 7 9 % of 208 + (16.9 × 304) = ?1/2 + 125 13 323

 100 × 208 + 17 × 304 = ?1/2 + 5 1300 323

16 + 16 – 5 = ?1/2

?1/2 = 27

? = 729 ≈ 730

Hence, option B is correct.

5
9.09% of 11.11% of 2430 = ?3 ÷ 289 + √( 4096 )
» Explain it
D
9.09% of 11.11% of 2430 = ?3 ÷ 289 + √( 4096 )

 2430 × 1 × 1 = ?3 ÷ 17 + 16 9 11

 270 = ?3 ÷ 17 + 4 11

 24.54 – 4 = ?3 17

 20.54 = ?3 17

21 × 17 = ?3

?3 = 357

? ≈ 7

Hence, option D is correct.
