P and Q have certain number of apples P says to Q if u give me 10 of your apple i will have the twice the number of apples left with you .Q replies if u give me 10 of your apples .I will the same number of apples left with you .Find the number of apples with P and Q separately (correction in the question)
Given:
Certain apples are divided between P and Q.
To find:
The number of apple with P and Q.
Solution:
1) Let the apples with P is x
and apples with Q is y
2) case1:
- x+10 = 2(y-10)
- x+10 = 2y - 20
- x-2y = -30 ------(I)
3) Case 2:
- x-10 = y+10
- x-y = 20 ------(II)
4) Subtract the equation (II) from (I)
x - y = 20
-x+2y = 30
y = 50
Putting the value of y in equation (II) we get,
- x=70
The number of apple with P and Q are 70 and 50 respectively.
