2 oranges 3 bananas and 4 apples cost Rs 15 3 oranges 2 bananas 1 apple costs Rs 10 what

2x+3y+4z = 15-------1
3x+2y+1z = 10-------2,
adding 1 and 2,
5x+5y+5z=25
So,
1x+1y+1z = 5rs
now,
3x+3y+3z = 5*3 = 15RS

2O+3B+4A = 15
3O+2B+1A = 10
add above
50+5B+5A=25 so
1O+1A+1B = 5
then
3O+3A+3B = 5*3=15 is the answer

given that all are in the ratio of

2:3:4=5

2x:3x:4x=15
2x+3x+4x=15
9x=15
x=5/3
required are in 3:3:3
3x:3x:3x
3*5/2+3*5/2+3*5/2=15
