Solutions:

 

Ans.1(4)       148, 847-92512 = 56,335

Ans.2(5)       44 + 79 + 53 – 57

                   =119

Ans.3(1)       27 – 30201 + 60504 +?2

                    = 30394

                   60531- 30201 +?2

                     = 30394

                   30330 +

?2=30394

                         ?2= 64

                         So, ? = 8

Ans.4(3)       37.7 × 11.4 × 15.3

                   = 6575.634

Ans.5(2)

                               

Ans.6(1)          Pattern is

                   100×5.5=550

                   550×4.5=2475

                    2475×3.5=8662.5

                   8662.5×2.5=21656.25

Ans.7(5)           Pattern is

                   18×2+32 =45   ,629×5+62=3181

                   45×3+42=151

                   151×4+52=629

Ans.8(2)

                         

Ans.9(2)          Pattern is

                   1×9+1=10

                   10×8+3=83
