Answer 1

Answer:

Rs 206

Step-by-step explanation:

Let cost of 1 kg sugar be x, 1 kg rice be y.

ATQ,

5x+7y=153       (1)

7x+5y=147       (2)

(1)+(2)

12(x+y)=300

x+y=25       (3)

(1)-(2)

2(y-x)=6

y-x=3     (4)

(3)+(4)

x+y+y-x=28

2y=28

y=14

By(3),

x=11

Now, ATQ

6x+10y=?

66+140

Rs 206
