Question

2 oranges 3 bananas and 4 apples cost rs.15 . 3 ornages 2 bananas 1 apple costs rs 10. what is the cost of 3 oranges 3 bananas and 3 apples

Answer 1

Let x be price of 1 orange
Let y be price of 1 banana
Let z be price of 1 apple

Thus,

2x + 3y + 4z = 15
3x + 2y + z = 10

Adding both equations

5(x + y + z) = 25

x + y + z = 5

Multiply both sides by 3

3x + 3y + 3z = 15

Thus 3 oranges 3 bananas and 3 apples cost 15 Rs
