Question 1 & 2
Question 1&2: The total weight is 255 gms for 2 apples and 3 oranges and that for 3 apples and 2 oranges is 285 gms. What is 1 apple and 1 orange weight individually ?
Let us suppose;
x= apple and y = orange
So according to statement;
We solve these two equations simultaneously ;
Multiply both sides of eq (1) by 3 and multiply both sides of eq (2) by 2;
Subtracting eq(6) from eq(5), we get;
put value of y in eq (5) [or (6)], we get;
so, weight of one orange is 39 gm and of one apple is 69 gm
