I’m pretty sure
8. would be false because BK would be 12 where as DF is 10.8
9. is true
If x represents the number of students from country C.
then 122% of x = 116,000
122/100 * x = 116000
Transposing the formula for x;
therefore x = 116000 * 100/122 = 95,082 students
Answer:
Upper quartile: 38
Lower quartile: 19
Answer 1:
It is given that the positive 2 digit number is 'x' with tens digit 't' and units digit 'u'.
So the two digit number x is expressed as,


The two digit number 'y' is obtained by reversing the digits of x.
So, 

Now, the value of x-y is expressed as:




So,
is equivalent to (x-y).
Answer 2:
It is given that the sum of infinite geometric series with first term 'a' and common ratio r<1 = 
Since, the sum of the given infinite geometric series = 200
Therefore,
Since, r=0.15 (given)



a=170
The nth term of geometric series is given by
.
So, second term of the series =
= ar
Second term = 
= 25.5
So, the second term of the geometric series is 25.5
