Final answer:
The total weight of the bag is 1250g + 650g + 1250g = 3150g.
Step-by-step explanation:
To find the weight of the bag, we need to add up the weights of the jalebis, potato chips, and biscuits.
1kg 250g is equal to 1250g, so the jalebis weigh 1250g.
650g is the weight of the potato chips.
1kg 250g is equal to 1250g, so the biscuits weigh 1250g.
Therefore, the total weight of the bag is 1250g + 650g + 1250g = 3150g.
