melody  (6 years ago)

total no of oranges be x
given no. of apples is 6
so remaining bananas is 30-x-6=24-x
now equation is 5*x+(24-x)*4=230-120
so x=14 oranges
24-x=10 bananas

surya  (6 years ago)

30-6=24
6*20=120
230-120=110
let x=orange
then 24-x=banana
x*5+(24-x)*4=110
x=14(ans)

rahul  (6 years ago)

let x,y,z no of fruits apple and orange and bananas.
so x+y+z=30
we know that x=6
x+y=30-6=24 --------------------(i)
the total cost of all fruit is
20x+sy+4z=230
we know that x=6
so,
5y+4z=230-120
5y+4z=110 -----------------------(ii)
solve equation i and ii you will get
y=14

Kalpana  (6 years ago)

Total fruits =30
No.of apples is 6
Oranges +bananas=24
Let oranges is x and bananas =24-x
Total cost is 230
Apples cost is 120
Cost of oranges and bananas is 230-120=110
Then 5x+(24-x)4=110
Then,x=14 which is no. Of oranges and 24-14=10 are bananas

lord voldmott  (6 years ago)

6×20 +5x+4x=230
5x+4x=110
as (30-6=24) so 5×14+4×10=110
satisfy the condition

let no. of orange=x
no. of banana=total-apple-orange= 30-6-x=24-x
cost of apple+orange +banana=230
(20*6)+(5x)+(4*(24-x))=230
120+5x+96-4x=230
216+x=230
x=14 (NO. of Oranges)

pratik prakash shaha  (6 years ago)

6 apples cost is rs 20 Rs.
let x,y be oranges and bananas respectively
here x and y cost Rs. 5 and Rs.4 respectively
cost of 6 apples=6*20
cost of x oranges=5x
cost of y bananas =4y
total cost of fruits=230 Rs.
There are 30 fruits into the basket
Therefore,form the equation
20*6+ 5x +4y=230 =>5x+4y=110
and
6+x+y=30 =>x+y=24
by solving these equations we get ,
x=14
and y=10
so the answer is 14 for oranges
and if bananas are asked the answer is 10.

Let an apple be X , an orange be Y and a banana be Z.
X+Y+Z=30
X=30
And
Cost of all fruits in basket is 230
Apple=20rs
Orange=5rs
Banana=4rs
20X+5Y+4z=30
By solving both equations we get
Y i.e total no. of oranges is 14

Arushi Bubber  (5 years ago)

Total number of fruits =30
Total no. of apples = 6
Fruits in basket : 6+orange+banana=30
so, orange+banana=30-6 =(24).
so, orange+banana=24
Now the equation is : orange= 24-banana-----(1)
Total cost of fruits in the basket=230.
Apple=total cost of apple* total no. of apples
Apples= 20 *6=120.
120+5*orange+4*banana =230
5*orange+4*banana=110.-----(2)
Now , Substituting Eq.1 in Eq 2:
5*(24-banana) + 4*banana=110
120-1 banana=110
-1 banana=-10
banana =10;
Substituting the value of banana in Eq.1 :
so, the no. of oranges=24-10= 14.

arafat  (2 years ago)

total no of oranges be x
given no. of apples is 6

20*6 + 5x+4y = 230

5x + 4y = 230-120

5x + 4y = 110 --- (1)

w.k.t that ,

x+y +z =30

x+y+6=30

x+y = 24 ---- (2)

solve 1 and 2 , we get

sub y = 10 in (2)

so , we get X = 14

( or)

24-y= orange

thank you
