A) 4360 B) 4460
C) 4560 D) 4660
 
Answer & Explanation Answer: B) 4460

Let the sum be Rs.P.then
P(1+R/100)^3=6690…(i) and P(1+R/100)^6=10035…(ii)
On dividing,we get (1+R/100)^3=10025/6690=3/2.
Substituting this value in (i),we get:
P*(3/2)=6690 or P=(6690*2/3)=4460
Hence,the sum is rs.4460.

Q:

A thief is noticed by a policeman from a distance of 200 m. The thief starts running and the policeman chases him. The thief and the policeman run at the rate of 10 km and 11 km per hour respectively. What is the distance between them after 6 minutes?

A) 100 m B) 150 m
C) 190 m D) 200 m
 
Answer & Explanation Answer: A) 100 m

Explanation:

Relative speed of the thief and policeman  =  (11 – 10) km/hr = 1 km/hr 

Distance covered in 6 minutes  = (1/60) x 6 km   = 1/10 km = 100 m

Therefore, Distance between the thief and policeman = (200 – 100) m = 100 m.

Q:

Find the odd one in the number series given below ?

17, 9, 10, 18.5, 35, 90

A) 9 B) 10
C) 18.5 D) 90
 
Answer & Explanation Answer: C) 18.5

Explanation:

The given series pattern follows

 

17       9       10       18.5       35       90

 

× 0.5 + 0.5,   × 1 + 1,   × 1.5 + 1.5,   × 2 + 2,   × 2.5 + 2.5

 

So here 

 

17x0.5 + 0.5 = 9

 

9x1 + 1 = 10

 

10x1.5 + 1.5 = 16.5

 

16.5x2 + 2 = 35

 

35x2.5 + 2.5 = 90

 

Here the odd man in the given series is 18.5
