Q. 1 1035 ÷ [(3/4) of (71 + 65) – 15 ¾] = ?
- 12
- 24
- 18
- 26
- None of these
Answer : 1
Solution :
1035 ÷ [(3/4)*136 – 63/4] = x
X = 1035 ÷ [102 – (63/4)]
X = 1035 ÷ [(408 – 63)/4]
X = 1035 ÷ (345/4)
X = 1035 *4/345
X = 12
Q. 2 (7 × 7)3 ÷ (49 × 7)3 × (2401)2 = 7?
- 7
- 5
- 6
- 8
- None of these
Answer : 2
Solution :
(7 × 7)3 ÷ (49 × 7)3 × (2401)2 = 7x
(72)3 ÷ (72 × 7)3 × (74)2 = 7x
76 ÷ 79 × 78 = 7x
76 – 9 + 8 = 7x
75 = 7x
X = 5

Q. 4 5 ¾ – 4 1/8 + 7 ½ – 3 3/8 = ?
- 4 3/7
- 6 5/6
- 7 ½
- 5 ¾
- None of these
Answer : 4
Solution :
5 ¾ – 4 1/8 + 7 ½ – 3 3/8 = x
X = (5 – 4 + 7 – 3) (3/4 – 1/8 + ½ – 3/8)
X = 5 [(6 – 1 + 4 – 3)/8]
X = 5 (6/8) = 5 (3/4)

Q. 7 (913 + 329 + 522 + 343) ÷ (18 + 24 – ? + 18) = 43
- 23
- 11
- 7
- 29
- 15
Answer : 2
Solution :
(913 + 329 + 522 + 343) ÷ (18 + 24 – x + 18) = 43
2107 ÷ (60 –x) = 43
(2107/43) = 60 – x
49 = 60 – x
X = 60 – 49 = 11
Q. 8 (3/7) of ? – (2/5) of (13/16) of 2160 = 12 % of 900
- 2150
- 1540
- 1960
- 1890
- 2370
Answer : 4
Solution :
(3/7)*x – (2/5)*(13/16)*2160 = (12/100)*900
(3x/7) – 702 = 108
(3x/7) = 108 + 702
(3x/7) = 810
X = (810*7/3) = 1890

- 776
- 614
- 590
Answer : 3
Solution :
(51/400)*2400 + (47/200)*800 + 2025 = (1125/25) + 4x
306 + 818 + 2025 – 45 = 4x
3104 = 4x
X = 3104/4 = 776
Q. 10 ∛157464 + √8836 – 45 % of 800 =? + (1188 ÷ 9) – 362
- 952
- 816
- 878
- 924
- None of these
Answer a
Explanation:
54 + 94 – (45/100)*800 = x + (1188/9) – 1296
54 + 94 – 360 + 1296 = x + 132
54 + 94 – 360 + 1296 – 132 = x
X = 952

X = 79
Q. 14 18 ¼ % of 17200 + 33 2/3 % of 1860 + 37 2/3 % of 19680 = ?
- 11178
- 13456
- 9824
- 10242
- 8454
Answer : 1
Solution :
(73/400)*17200 + (101/300)*1860 + (113/300)*19680= x

Q. 15 586 × 9234 ÷ 48 % of 950 = 36 × 750 ÷ 4 + ? + 4500 .
- 25
- 728
- 5
- 75
- 474
Answer : 3
Solution :
586 × [9234 ÷ ((48/100)*950)] = 36 × (750/4) + x + 4500
586*(9234/456) = 6750 + x + 4500
11866.5 – 11250
X = 616.5
Q. 16 1323 ÷ (27 % of 700) = 35 × 7 3/5 of (? ÷ 190)
- 7
- 9
- 4
- 5
- 8
Answer : 4
Solution :
1323 ÷ [(27/100)*700] = 35 × (38/5)*(x/190)
1323 ÷ 189 = 35 × (38/5)*(x/190)
(7*5*190)/(35*38) = x
X = 5

- 156
- 218
- 189
- 130
- None of these
Answer : 4
Solution :
√13225 + ∛205379 + 52 % of 700 = 408 + x

Q. 20 492 ÷ 14 × 8 + 582 = 4 × ? – 15 % of 2480
- 1489
- 1277
- 1645
- 1823
- None of these
Answer : 2
Solution :
(49*49*8)/14 + 582 = 4x – (15/100)*2480
