Answer:
They started with 7,142.86 rupees. They spent 714.29 rupees on food.
Step-by-step explanation:
We know that 30% of their rupees were spent. That means that 70% of their money is left, which is 5000 rupees. So:
0.70x = 5000
x = 5000/0.70 = 7,142.86
They had 7,142.86 rupees to start with. They spent 10% of the total on food.
7,142.86 x 0.10 = 714.29
