A.14 B.14 1/2 C.14 3/4 D.15 1/2 E.None of these
Answer: E
Explanation:
8 2/3 + 6 4/5 = (8 + 6) + (10/15 + 12/15) = 14 + 1 7/15 = 15 7/15
2. 7 2/5 of 110 / ? = 844
A.22 B.24 C.30 D.28 E.None of these
Answer: C
Explanation:
? = 844 - 7 2/5 of 110 = 844 - 37 * 22 = 30
3. 2 + [2 + {2 + (2 + (2 + 23)}] = ?
A.17/4 B.33/4 C.65/4 D.129/4 E.None of these
Answer: B
Explanation:
2 + [2 + {2 + (2 + (2 + 23)}]
= 2 + 6 + 1/4 = 33/4
4.(24 * 5 * 7 * 9) / ? = 216
A.15 B.20 C.25 D.35 E.None of these
Answer: D
Explanation:
? = (24 * 5 * 7 * 9) / 216 = 35
5. (98 / 7 / 2) / ? = 14
A.1/2 B.1/3 C.1/4 D.1/5 E.None of these
Answer: A
Explanation:
? = (98 / 7 / 2) / 14 = 1/2
6.(815 / ?) / 100 * 28 * 3 - (815 * 14 * 6)/100 = 1680
A.2000 B.3000 C.4000 D.6000 E.None of these
Answer: A
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
7. 32% of 425 - ?% of 250 = 36
A.20 B.40 C.60 D.80 E.70
Answer: B
Explanation:
32/100 * 425 - x/100 * 250 = 36
=> x/100 * 250 = 136 - 36 = 100
=> x = (100 * 100)/250 = 40
8. 2003 * 2004 - 2001 * 2002 = ?
A.8000 B.8010 C.8020 D.8040 E.8030
Answer: B
Explanation:
(2000 + 3)(2000 + 4) - (2000 + 1)(2000 + 2) = ?
Since (2000 * 2000) - (2000 * 2000) is equal to zero. ?
= (8000 + 6000 + 12) - (4000 + 2000 + 2)
=> ? = 14012 - 6002 = 8010
9. 2222.2 + 222.22 + 22.222 = ?
A.2466.462 B.2664.642 C.2464.462 D.2466.264 E.2466.642
