Answer 1

Answer:

Sugar 40 rs kg

tea = 300rs kg

Step-by-step explanation:

corection

1.5 kg tea and 5 kg sugat

expense = rs 700

fare = 50

paid for tea and sugar = 700-50=650

let say tea price = T rs/kg

sugar Price = S rs/kg

1.5T + 5S = 650. eq1

2T + 7S = 880. eq2

3*eq2-4*eq1

S = 2640-2600

S = 40

2T + 280 = 880

T = 300
