Answer :
Answers of all the six questions are written below.
Step-by-step explanation:
1. Six
2.Five
3. Let the age of Tina be x and the age of meena be 42- x
Ratio of there ages is given as 3:4
A.T.Q
x/42-x = 3/ 4
4x = 126 - 3x
4x + 3x = 126
7x = 126
x = 126/7
x = 18
After four years
Age of tina = x + 4
Age of Meena = 42 - x + 4
Present age of Tina = x + 4
= 18 + 4
= 22
Present age of Meena = 42 -x + 4
= 42 - 18 + 4
= 28
4. 6,13,28,59,122,249
5. Kamal is maternal uncle of Ravi.( As Ravi's mother is Kamal's sister).
6.Total no. of students in the class = 66
As Rahul is 19th from top so 18 students are ranked above him and As rahul is also 48th from bottom 47 students are ranked below him.
So,
18 + 1( Rahul himself ) + 47 = 66
