Answer» Let the cost of one pencil = Rs. xLet the cost of one eraser = Rs. y Romila purchases 2 pencils and 3 erasers for Rs. 9 Cost of 2 pencils = 2xCost of 3 erasers = 3yTotal Cost = Rs. 9 So, we have: 2x + 3y = 9 ---(1) Sonali purchases 4 pencils and 6 erasers for Rs 18. Cost of 4 pencils = 4xCost of 6 erasers = 6y Total Cost = 18 So, we have: 4x + 6y = 18So, 2(2x + 3y) = 18So,2x + 3y = 9----(2)

Answer»

Let the cost of one pencil = Rs. xLet the cost of one eraser = Rs. y

Romila purchases 2 pencils and 3 erasers for Rs. 9

Cost of 2 pencils = 2xCost of 3 erasers = 3yTotal Cost = Rs. 9

So, we have:

2x + 3y = 9 ---(1)

Sonali purchases 4 pencils and 6 erasers for Rs 18.

Cost of 4 pencils = 4xCost of 6 erasers = 6y

Total Cost = 18

So, we have:

4x + 6y = 18So, 2(2x + 3y) = 18So,2x + 3y = 9----(2)
