x and x+4 are the numbers
3x=2(x+4)
3x=2x+8
3x-2x=8
x=8
x+4=12
The amount of interest Molly will earn after 5 years on a deposit of
compounded annually over 5 years is 
First, we need to find the future value of her investment, then we subtract the original deposit from it to get the amount of interest she will get at the end of 5 years.
The future value of an investment that is compounded annually is given by

where

Substituting the available values into the formula and solving

The interest Molly will earn after 5 years is

Therefore, the amount of interest Molly will earn after 5 years on a deposit of
compounded annually over 5 years is

The key is Esther travelled the same distance - x - in both her morning and evening commute.
45(time she took in the morning, or p) = x
30(time she took in the evening, or q) = x
Therefore 45(p) = 30(q), or divide both sides by 5 and get 9(p) = 6(q). I know you can divide it further, but these numbers are small enough and it's not worth the time.
Since the whole trip took an hour, (p + q) = 60min, and so, p = 60-q.
Therefore 9(60-q) = 6q or 540-9q = 6q. So 540 = 15q, which makes q = 36. If q = 36, then by (p+q)=60, p (the time she took in the morning) must equal 24.
45 miles per hour, her speed in the morning, times (24/60) hours, her time, makes 18 miles travelled in the morning. If you check, 30 miles per hour times (36/60) hours also makes 18 miles in the evening.

Answer:
Step-by-step explanation:
Alina=2x---eq(1)
Asim=5x----eq---(2)
So,we get
2x+5x=210
7x=210
x=30
Now,Putting '30' in eq 1 and eq 2
2*30=60
5*30=150
Therefore Alina got 60 Rs while Asim got 150 Rs
d=28g I might be wrong, but we can find this by dividing 140 by five, which equals 28.
