1042 –  324
 = ? ÷ 3

301 – 
168 – 
544 + 
1042 –  18
 = ? ÷ 3

301 – 
168 –

Hence, option (B) is correct.
 
2
What will come in the place of question mark (?) in the following question:

1089 ÷ 1728 ÷ 11 + 225 = ?2 - 652.75
» Explain it
B
1089 ÷ 1728 ÷ 11 + 225 = ?2 - 652.75
 
1089 ÷ 12 ÷ 11 + 15 = ?2 – 652.75
 
8.25 + 652.75 + 15 = ?2
 
661 + 15 = ?2
 
?2 = 676
 
? = 26

Hence, option B is correct.
3
What will come in the place of question mark (?) in the following question:

72.9 ÷ 81 × 100 = ?1/2 ÷ 324 + 64
» Explain it
A
72.9 ÷ 81 × 100 = ?1/2 ÷ 324 + 64
 
72.9 ÷ 81 × 10 = ?1/2 ÷ 18 + 4
 
729 ÷ 81 = ?1/2 ÷ 18 + 4
 
9 – 4 = ?1/2 ÷ 18
 
5 × 18 = ?1/2
 
?1/2 = 90
 
? = 8100

Hence, option A is correct.
4

48.3 × 289 ÷ 3.4 ÷ 23 ÷ 68 × 21 = ?3 + 28.125 
 
483 × 289 ÷ 34 ÷ 23 ÷ 68 × 21 = ?3 + 28.125 
 
441/ 8 = ?3 + 28.125
 
55.125 – 28.125 = ?3
 
?3 = 27
 
? = 3

Hence, option B is correct.
5

4 1  + 2 7  – 5 11  = ? + 2  4
3 4 3 3

4 1  + 2 7  – 5 11  –2 4  = ?
3 4 3 3

? = (4 + 2 – 5 – 2) +  1  +  7  –  11  –  4
3 4 3 3

? = – 1 +  4 + 21 – 44 – 16
12

? = – 1 +  (-  35 )
