15) Suppose Tom is 16 year old, and he is four times older than his brother Robert. How old Tom would be when he is twice as old as her brother?

If Tom is 16 year old and he is 4 times older than his brother Robert, then currently his brother age would be 16/ 4 = 4. So his brother is 4 year old.

This makes Tom 12 years older than her brother

Now, Tom will be double his brother age when Robert is 12 year old.

i.e 12X2 = 24.  Which means when Tom will be 24 year old his brother age will be 12.

5+8= 13

8+13=21 and so on

17) What will be the next number 5,10,19,32,49,70 ….?

19-10 = 9


49-32= 17


?- 70= 25

For each answer 5, 9, 13 there is a difference or increase of 4, so our next increment will be 25.

So, ? -70 = 25

25+70= 95
