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

In following question, A number series is given with one term missing. Choose the correct alternative

9 , 12 , 11 , 14 , 13 , x , 15

9 , 12 , 11 , 14 , 13 , x , 15

Alternately we add 3 and subtract 1. Thus,

9 + 3 = 12, 12 - 1 = 11, 11 + 3 = 14

and so on. Missing number = 13 + 3 = 16..

In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options.

QPO, SRQ, UTS, WVU, ?

Each term in the series consists of three consecutive letters in reverse order. The first letter of each term and the last letter of the next term are the same.

Find the next number in the following sequence:

2, 5, 10, 17, 26...?

2, 5, 10, 17, 26...?

Each term is 1 more than a square. That is, the pattern is given by:

n = 1, 2, 3, 4, 5

n

n

So, the n

n

In following number series, either one term is missing or is incorrect.

Choose correct answer from options 2, 3, 5, 8, 13, 34

Choose correct answer from options 2, 3, 5, 8, 13, 34

Clearly, each term of the series is the sum of the preceding two terms.

Now 8 + 13 = 21 and 13 + 21 = 34.

So, the term 21 is missing..

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

ba _ b _ aabb _ a _ _ a _ bb

The series is baab / baab / baab / baab / b. Thus, the pattern baab is repeaated

The present age of three persons are in proportion 4:7:9. Eight years ago the sum of their ages is 76. Find their present ages?(in years)

Let the present ages be 4x,7x,9x years respectively.

Then (4x-8)+(7x-8)+(9x-8)=76

20x=100

x=100/20

x=5

There present ages be 20,35,45 years respectively.

The sum of Ages of jhonny and today is 50. Find years ago, Charlie age was three times as jhonny age. How old are Johnny now?

1st condition

J + C = 50... Equation 1

2nd condition

3J - 5 = C - 5

3J - 3 = 10... Equation 2

by solving the equation

J = 15 and C = 35
