Answer 1

Step-by-step explanation:

1. 7kg onion=Rs 140

12kg onion = Rs140×12=1680

Answer 2

Answer:

7kg = Rs 140

1kg = Rs 20

12kg = Rs 240

600 rs = 15 bunches

1 rs = 15/600 bunches

1280 rs = (15x1280)/600 = 32 bunches

9 cows = 13500g food

1 cow = (13500/9)g

12 cows = 18000g or 18kg

12 quintals of soyabean = 36000 rs

1 quintal = 3000 rs

8 quintals = 24000 rs

2 mobiles = 16000 rs

1 mobile = 8000 rs

13 mobiles = 104,000 rs
