A. 80000
B. 90000
C. 105000
D. 85000
Explanation:
9 * 3000 – 10.1 * 1100 + 8238 – 4302
31 * 3000 – 1010 * 11 + 8298 – 4302
93000 + 8298 – 11110 – 4302 = 101298 – 15412
= 85886 = 85000

A. 33500
B. 23500
C. 22500
D. 24500
Explanation:
421 * 0.9 + 130 * 101 + 10000
= 378.9 + 1313 + 10000 = 23508.9 = 23500

A. 10
B. 15
C. 7
D. 16
Explanation:
[8 + {(21 * √9/441 – 1 /5 of 60% – 1/5) * 625 + 7} ÷ 4] = ?
=[8 + [(2/5 * 3/5 – 1/5) * 625 + 7} ÷ 4] = ?
=[8 + {(6 – 5 /25) * 625 + 7} ÷ 4 = ?
=[8 + {32} ÷ 4] = ? = 16

A. 7
B. 10
C. 15
D. 49
Explanation:
[3/7 of {21 * (33.33% of (27 + 3) ÷ 5) – 7} – 8] = ?
= [3/7 of {21 * (1/3 * 30 ÷ 5) – 7} – 8] = ?
= 3/7 of [{21 * 2 – 7} – 8] = ? => {3/7 * 35 – 8} = ? => 7

A. 20
B. 8
C. 10
D. 15
Explanation:
[10 + { 4 * (2/3 + 1/4 * √144/121 + 23) ÷ 12 + 5} – 3] = ? [10 + { 4 * (11/12 * 12/11 + 23) ÷ 12 + 5 } – 3] = ?
= [10 + {4 * 24 ÷ 12 + 5} – 3] = ?
= [10 + 13 – 3] = ? = > 20

A. 25
B. 125
C. 241/5
D. 253/5
Explanation:
[50 – {20 + 60% of (26/13 + 24/12 + 21) – 2} + 8] = 625/x => [50 – {20 + 3/5 of (25) – 2} + 8] = 625/x
=> [50 – 33 + 8] = 625/x => x = 25

A. 90
B. 270
C. 810
D. 240
Explanation:
16.66% of 33.33% of 66.66% of x = 30
= 1/6 of 1/3 of 2/3 of x = 30
=> (30 * 6 * 3 * 3)/2 => x = 810

A. 1037.50
B. 1157.50
C. 103.75
D. 1038
Explanation:
12.5 + 10 1/4 of 100 ÷ 10% of 10
= 12.5 + 41/4 of 100 ÷ 10/100 of 10
= 12.5 + 41(25) ÷ 1 = 12.5 + 1025 = 1037.5

A. 9/8
B. 3/10
C. 3/5
D. 3/8
Explanation:
(6 – 2 * 3 + 6) / (2 + 6 * 3 – 4) = (6 – 6 + 6) / (2 + 18 – 4)
= 6/16 = 3/8

A. 4 9/11
B. 37
C. 47
D. 74
Explanation:
2/3 * 5 1/2 * 2 * 7 5/6 * 9/11
2/3 * 11/2 * 2 * 47/6 * 9/11 = 47
