Question

cost of 10 orange and 12 chikoos is ruppes 28 but cost of 12 orange and 10 chikoos is ruppes 1 less ,than find the cost of 2 orange and 4 chikoos​

Answer 1

Answer:

let orange = x

and chikoss = y

a/q 10x + 12y =28 --------eq 1

Now

a\q 12x + 10y = (28-1) one less the previous price

12x + 10y = 27 ------ eq 2

now solve both the equation

multiple eq1 x12 and eq2 x10

subtract (ii) from (I)

120x + 144y = 336

-( 120x + 100y = 270)

-------------------------------------

44y = 66

y = 3/4 ------- 0.75 rupes

put value of x and find x
