Answer 1

Answer:

Potato = 6.5 rs

Tomato = 3.5 rs

Step-by-step explanation:

Let 1 kg of potato cost X and 1 kg of tomato cost y.

Case I:-

4x + 3y = 36.50

Case II :-

3x + 2y = 26.50

By elimination method,

2(4x + 3y)-3(3x + 2y)=2(36.50)- 3(26.50)

8x - 9x = 73 - 79.5

X = 6.5 rs

Therefore, y = 3.5 rs
