Let the no of oranges with 'A' and 'B' equal to X and Y respectively
Then,according to your question Y gives 10 oranges to X,then X will have twice the number of oranges left with Y
Written numerically =>
X + 10 = 2(Y - 10)
And if X gives 10 oranges to Y,then Y will have the same number of oranges as X (is left with)
Written numerically=>
Y + 10 = X - 10 =>
Y + 10 + 10 = X
X = Y + 20
Taking the previous equation and substituting the values(of X),we get
X + 10 = 2(Y - 10) =>
(Y + 20) + 10 = 2Y -20 =>
Y + 30 = 2Y - 20
30 + 20 = 2Y - Y
50 = Y
Taking one of the preceding equations.
X = Y + 20
X = 50 + 20
X = 70
Hence,A has 70 oranges whereas B has 50 oranges.
