(492 * 182) / 324 = ________?
A. 49
B. 98
C. 492
D. 982
Explanation:
(492 * 324) / 324 = 492
33/4 of 4500 + ? = 118500
33/4 of 4500 + ? = 118500
A. 8.1375 * 104
B. 2.4123 * 104
C. 5.124 * 104
D. 6.125 * 104
Explanation:
? = 118500 – 33/4 * 4500 = 8.1375 * 104
2 + [2 + {2 + (2 + (2 + 23)}] = _____?
2 + [2 + {2 + (2 + (2 + 23)}] = _____?
A. 17/4
B. 33/4
C. 65/4
D. 129/4
Explanation:
2 + [2 + {2 + (2 + (2 + 23)}]
= 2 + 6 + 1/4 = 33/4
7 2/5 of 110 / ? = 844
7 2/5 of 110 / ? = 844
A. 22
B. 24
C. 30
D. 28
Explanation:
? = 844 – 7 2/5 of 110 = 844 – 37 * 22 = 30
8 2/3 + 6 4/5 = _____?
8 2/3 + 6 4/5 = _____?
A. 14
B. 14 1/2
C. 14 3/4
D. None of these
Explanation:
8 2/3 + 6 4/5 = (8 + 6) + (10/15 + 12/15) = 14 + 1 7/15 = 15 7/15
(815 / ?) / 100 * 28 * 3 – (815 * 14 * 6)/100 = 1680
(815 / ?) / 100 * 28 * 3 – (815 * 14 * 6)/100 = 1680
A. 2000
B. 3000
C. 4000
D. 6000
Explanation:
Let 815 + ? be k
=> 84k/100 – (815 * 84)/100 = 1680
=>84(k/100 – 815/100) = 1680
=> (k – 815)/100 = 20 => k = 2815
k = 815 + ? = 2815 => ? = 2000
20% of 40 + ? % of 80 = 120
20% of 40 + ? % of 80 = 120
A. 140
B. 120
C. 160
D. 180
Explanation:
20% of 40 + ? % of 80 = 120
=> 800/100 + ?/100 * 80 = 120
=> ? = 140
