A thief goes away with a MARUTHI car at a speed of 40 kmph. The theft has been discovered after half an hour and the owner sets off in a bike at 50 kmph when will the owner over take the thief from the start ?

Correct Answer: 12

Explanation:

The given series follows a pattern that,

 

$$\begin{gathered} 4 + 3 2 = 4 + 9 = 13 \\ 13 + 5 2 = 13 + 25 = 38 \\ 38 + 7 2 = 38 + 49 = 87 \\ 87 + 9 2 = 87 + 81 = 198 \end{gathered}$$ 

 

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)
