In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative. _ aba _ cabc _ dcba _ bab _ a

The series is aababcabcddcbacbabaa. Thus, the letters equidistant from the beginning and the end of series are the same.

Walking at the speed of 4 kilometre per hours Susan covers certain distance in 2 hour 45 minute. Running at the speed of 16.5 km per hour the Suan will cover the same distance in?

D=vxt

Here time= 2 hr 45 min=11/4 hr

Distance=4*11/4=11 km

New speed=16.5

Therefore time=D/v

=(11/16.5)60=40 minutes

Complete the Given Series

Which is the number that comes next in the sequence:

0, 6, 24, 60, 120, 210 ?

Which is the number that comes next in the sequence:

0, 6, 24, 60, 120, 210 ?

Clearly, the given series is 1

So, Next number = 7

Hence, the answer is (c)..

In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

c _ bba _ cab _ ac _ ab _ ac

The series is cabbac / cabbac / cabbac. Thus, the pattern cabbac is repeated..

In alphabet series, some alphabets are missing which are given in that order as one of the alternatives below it. Choose the correct alternative.

abca _ bcaab _ aa _ caa _ c

The series is a / bcaa / bcaa / bcaa / bcaa / bc. Thus, the pattern bcaa is repeated.

The present ages of Lewis and Brown is 1:2. Three years from now their ages be in ratio 3:5. Find the age of Brown after 5years?

Let

Brown=b

Lewis=l

Present ages be b/l=1:2

2l-b=0....eq(1)

After three years l+3/b+3=3:5

5l-3b=6

By resolving eq

b=12

l=6

After 5 years l= 11

b=17
