तो कितने रुपए बचे....?

Answer 1

80×50%=40
40×25%=10
40-10=30
therefore 30 rupees left

Answer 2

Answer: The remaining amount is 70.

Explanation:

The total amount is 80.

50% of 80 is,

$80\times\frac{50}{100}=40$

So, 40 remains same and 25% of another 40 spent.

25% of 40 is,

$40\times\frac{25}{100}=10$

So, the total expense is 10 and the amount reduced by 10 rupees.

The remaining amount is the difference of total amount the expenses.

$\text{Remaining Amount}=80-10=70$

Therefore, the remaining amount is 70 rupees.
