Answer 2

Answer:

The correct option is cannot be determined

Step-by-step explanation:

Given,

Shikha can purchase 5 breads, 7 bananas, and 13 eggs for Rs.236

and  2 breads, 3 bananas, and 6 eggs for Rs. 101

To find,

The cost to purchase 1 bread, 3 bananas, and 9 eggs at the same rate

Solution:

Let 'x' be the cost of 1 bread, 'y' be the cost of 1 banana and 'z' be the cost of 1 egg.

Since, Shikha can purchase 5 breads, 7 bananas, and 13 eggs for Rs.236,

5x+7y+13z = 236 -------------------(1)

2 breads, 3 bananas, and 6 eggs for Rs. 101,

2x+3y+6z = 101 ------------------(2)

To find the cost of 1 bread, 3 bananas, and 9 eggs, we need to find the cost of one bread, the cost of one banana, and the cost of one egg

That is we need to find the value of variables x, y, and z

Since there are three variables, we need to have three equations to find the variables.

Since here we have only two equations, the required amount can not be determined

Hence the correct option is cannot be determined
