Answer 2

6 goose eggs worth Rs 21 if 4 chicken eggs and 2 goose eggs are worth Rs 15 and 2 chicken eggs and 4 goose eggs are worth Rs 18

Given:

• 4 chicken eggs and 2 goose eggs are worth Rs 15
• 2 chicken eggs and 4 goose eggs are worth Rs 18

To Find:

• How much are 6 goose eggs worth

Solution:

Step 1:

Assume that 1 chicken eggs worth = Rs x  and 1 goose egg worth Rs y

Step 2:

Create an Equation for 4 chicken eggs and 2 goose eggs are worth Rs 15

4x + 2y = 15 ... Eq1

Step 3:

Create an Equation for 2 chicken eggs and 4 goose eggs are worth Rs 18

2x + 4y = 18 ... Eq2

Step 4:

2 * Eq2 - Eq1  

4x + 8y  -  4x - 2y  = 36 - 15

=> 6y = 21

Hence 6 goose eggs worth Rs 21
