#### Question No 1

Look at this series: 3, 4, 7, 8, 11, 12, . . .
What number should come next ?

Solution!
This alternating addition series begins with 3;
then 1 is added to give 4;
then 3 is added to give 7;
then 1 is added, and so on.
Rule = (first number + 1), (second number + 3), (third number + 1), (fourth number + 3)...
Now The series is 3, 4, 7, 8, 11, 12...
(3 + 1 = 4), (4 + 3 = 7), (7 + 1 = 8), (8 + 3 = 11), (11 + 1 = 12), (12 + 3 = 15)...

#### Question No 2

#### Question No 3

Sherry's math test had 100 problems, 40 arithmetic, 30 algebra, 30 geometry problems. Although he answered 30% of arithmetic, 40% of algebra and 70% of geometry problems correctly, still he got less then 50% marks. How many more questions he would have to answer more to get passed.

Solution!
Arithmetic: 30% of 40 = 12
Algebra : 40% of 30 = 12
Geometry : 70% of 30=21
Total correct = 12+12+21=45
50-40=5 marks needed to pass.

#### Question No 4

The ratio of two brothers John and Harry is 4 / 5 . However if the age of John before 10 years and that of Harry after 10 years than the original ratio is reversed. What is the age of Harry?

Solution!
let's John age =a and Harry age = b
Given that
a/ b =5 / 4
4 a=5 b
4a- 5b =0..... equation 1
and also given that
a - 10 / b + 10 =4 / 5
a5 - 50= 4b+40
5 a- 4b= 90 .......equation 2
By solving both equation
so, Harry is 40 years old.
