hi,

i think

it can be 15 bcoz

2x+3y+4z=15


3x+2y+z=10


adding


5x+5y+5z=25


x+y+z=5 that is for 1 orange ,1 bannana and 1 apple requires 5Rs.


so for 3 orange ,3 bannana and 3 apple requires 15Rs.


i.e. 3x+3y+3z=15........

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

adding and then dividing,

x+y+z=5;
so,
for 3x+3y+3z=15..


So, answer is 15

Adding Eqn 1 & 2
5 Orange + 5 Banana + 5 Apple=25
so...
1 Orange + 1 Banana + 1 Apple=5
That is ....
3 Orange + 3 Banana + 3 Apple=15

  2 O+3 B+4 A=15
 +
  3 O+2 B+1 A=10
----------------------------
 5 O+5 B+5 A=25

therefore, O+B+A=5
and,         3O+3B+3A=15

ans:15
here eq
2x+3y+4z=15
3x+2y+z=10
onadding both eq 5(x+y+z)=25=>x+y+z=5
asking
3x+3y+3z=??
3(x+y+z)=3(5)=15

2 oranges + 3 bananas + 4 apple=15RS
3 oranges + 2 bananas + 1 apple=10RS
so now
5 oranges+ 5 bananas + 5 apples = 25RS
so
5( 1 orange +1 banana + 1 apple)=5(5)
5 gets cancelled
so since they asked 3 oranges + 3 bananas + 3 apples =3(1 orange + 1 banana + 1 apple) = 3(5)
= 15

Hi
I think
I can be 15 bcz
2x+3y+4z=15
3x+2y+1z=10
So adding
5x+5y+5z=25
Let 5 LCM
5(x+y+z)=25
x+y+z=5
So 1 orange, 1 banana, 1 apple is cost 5 Rs.
Then 3 orange, 3 banana, 3 apple costs 15 Rs.
its solved. Ans= 15
