Ans: (c) 7342015 x 9999 =7342015 (10000-1) =73420150000-7342015 =73412807985

Ans : (d) प्रश्न से, 69696 × 9999 = 69696 × (10000-1)
= 696960000-69696
= 696890304

Ans: (c) 19170÷54÷5
= 355 +5 = 71
NOTE: इस प्रकार के प्रश्न में बाएँ से दाएँ भाग देते है।

Ans: (d) 33333 × 9999 = 33333 (10000-1)
= 333330000-33333
= 333296667

Ans: (d) 66666 × 9999
= 66666 (10000-1)
= 666660000-66666
= 666593334

Ans: (d) 9876+34.567 - ? = 9908.221
9910.567-?= 9908.221
? = 9910.567 - 9908.221
? = 2.346

Ans: (a) 1093 × 1093
= (1000+93) × 1093
= 1093000+ 1093 x 93
= 1093000 + 1093 × (100-7) = 1093000+ 109300-1093 × 7
= 1093000 + 109300-1093 (10-3)
=1093000+109300-10930+3279
= 1205579-10930 = 1194649

Ans: (c) - 261 + (- 380) - (- 521) + 821 - (- 121)
= - 261 - 380 + 521 + 821 + 121
= 641+1463 = 822

Ans. (b) {20 - (25 - 33)} ÷ {- 5 × 4 - (- 6)} + 56 ÷ (- 27 + 13) = ?
= {20 + 8} ÷ {- 20 + 6} + 56 ÷ (- 14)
= {28} ÷{- 14} - 4
=-2-4 = -6

Ans: (a) 2 - [3 - {6 - (5 - 4 - 3 + 10)}]
= 2 - [3 - {6 - (8)}]
= 2 - [3 - (- 2)]
= 2-5
= -3

Ans: (b )= 2550 - [510 - {270 - (90 - 80 + 70)}]
= 2550 - [510 - {270 - 80}]
= 2550 - [510 - 190]
= 2550-320
= 2230

Ans: (d) = 23 - [23 - {23 - (23 - 23 + 23)}]
= 23 - [23 - {23 - 23 + 23 - 23}] = 23 - [23 + 0]
= 23-23-0

Ans: (a) 27 - [38 - {46 - (15 - 13 - 2)}]
27 - [ 38 - { 46 }]
= 27 - [38 - 46] = 27 - [- 8] = 27 + 8 = 35

Ans. (c) 77 ÷ [46 - {66 - (52 - 63 ÷ 9 × 3)}]
= 77 ÷ [46 - {66 - (52 - 7 × 3)}]
= 77 ÷ [46 - {66 - (31)}]
= 77 ÷ [46 - {35}]
= 77 ÷ [11]
= A = 7

Ans. (c) = 140 ÷ [61 - {36 - (40 - 60 ÷ 12 × 6)}]

= 140 ÷ [61 - {36 - (40 - 5 × 6)}]
= 140 ÷ [61 - {36 - (10)}]
= 140 ÷ [61 - 26]
= 140 ÷ 35 = 4

Ans : (b)

(-5) ( 20 - (- 2) × (- 8) =?
=(-5) ( 20 - 16 )
= (- 5) × 4
= - 20
