Answer 1

1 ) [ 2400 - 75 x ( 96 : 3 : 2 ) ] x 235  = 

= [ 2400 - 75 x ( 32 : 2 ) ] x 235 

= [ 2400 - 75 x 16 ] x 235

= [ 2400 - 1200 ] x 235 

= 1200 x 235

= 282000

-------------------------------------------------

2 ) 1000 - [ ( 250 : 25 + 330  : 3 ) - ( 30 x 2 - 5 x 8 ) ] x 4 = 

= 1000 - [ ( 10 + 110 ) - ( 60 - 40 ) ] x 4 

= 1000 - [ 120 - 20 ] x 4  

= 1000 - 100 x 4 

= 1000 - 400

= 600

-----------------------------------------------


3 ) ( 220 : 4 + 6 ) x 100 - [ 25 + ( 299 - 77 x 3 ) ] + 12 =

= ( 55  + 6 ) x 100 - [ 25 + ( 299 - 231 ) ] + 12

= 61 x 100 - [ 25 + 68 ] + 12 

= 6100 - 93 + 12 

= 6007 + 12 

= 6019

-------------------------------------------

4 ) [ 700 - ( 505 - 135 x 2 - 38 x 3 ) x 2 ] - 100 = 

= [ 700 - ( 505 - 270 - 114 ) x 2 ] - 100 

= [ 700 -  ( 235 - 114 ) x 2 ] - 100 

= [ 700 - 121 x 2 ] - 100 

= [ 700 - 242 ] - 100 

= 458 - 100 

= 358 

------------------------------------------

5 ) 32 x 51 : 8 x 200 - [ 775 : 25 x ( 172  - 85 ) ] = 

= 1632 : 8 x 200 - [ 31 x 87 ] 

= 204 x 200 - 2697 

= 40800 - 2697 

= 38103 

---------------------------------------------

6 ) [ ( 24 x 8000 - 190000 ) : 1000 x 63 - 36  ] : 45 = 

= [ ( 192000  - 190000 ) : 1000 x 63 - 36 ] : 45 

= [ 2000 : 1000 x 63 - 36 ] : 45 

= [ 2 x 63 - 36 ]  : 45 

= [ 126 - 36 ] : 45 

= 90 : 45 

= 2 

Answer 2
