Correct Answer: 12
Explanation:
The given series follows a pattern that,
Hence, the odd man in the given number series is 12.
Correct Answer: 500
Correct Answer: 12 × 6 × 7
Correct Answer: 502
Explanation:
The given series is 12, 48, 168, 502, 1260
12
12 x 4 = 48
48 x 3.5 = 168
168 x 3 = 504
504 x 2.5 = 1260
Hence, the odd man out in the given series is 502.
Correct Answer: 8 months
Explanation:
Suppose B joined for x months . Then, ( 85000 * 12 )/(42500 * x) = 3. or x = (85000 * 12) / (42500 * 3) = 8.
So, B joined for 8 months.
Correct Answer: 15
Correct Answer: 12.4
Explanation:
The given series 24.3, 23.1, 20.7, 17.1, 12.4 follows a pattern that
24.3
24.3 - 1.2 = 23.1
23.1 - 2.4 = 20.7
20.7 - 3.6 = 17.1
17.1 - 4.8 = 12.3 not 12.4
Hence, the odd man or odd number in the given series is 12.4
Correct Answer: Rs.900
Explanation:
Let 4A = 6B = 1OC = k. Then, A = k/4, B = k/6, and C =k/10 .
A : B :C = k/4 : k/6 : k/10 = 15 : 10 : 6.
Hence, C's share (4650 * 6/31) = Rs, 900.
Correct Answer: 105/112
Correct Answer: 978
Explanation:
The given series is 1000, 1012, 988, 1024, 978
1000
1000 + 12 = 1012
1012 - 24 = 988
988 + 36 = 1024
1024 - 48 = 976 (Not 978)
