– (? – 35) =40      or      + ( ? – 35) =40

35- 40 =?                         ? = 40 +35

-5 =?                                  ?= 75

3) Answer: b)

(5555 / 50) + (645 / 25) + (7982/ 52)

= (1111/10) + (129/5) + (307 / 2)

= (1111 + 258 + 1535) /10

= 2904/10

= 290.4

4) Answer: d)

[4√6 × 10 √6] –  144

= 40×6 – 144

=240 – 144 = 96

5) Answer: a)

44 × 135 ÷ 15 – ? = 29

44 × 9 -? = 29

396 – 29 = 367

6) Answer: c)

17/64 +⅜-1/16

= (17+24 – 4)/64

= 37/64

7) Answer: b)

(8 × 1458 × 12) / (144 × 2 × 9) +? = 56

54 + ? = 56

?=2
