Question

80 रुपये के 50% में से 25% रुपये खर्च हो जाते है तो कितने रुपये बचते हैं

Answer 1

Answer:

Rs 70 has been left.

Explanation:

The initial amount is given as Rs 80.

Now, 50% of 80 is given by

$\frac{50\times 80}{100} \\\\=\frac{80}{2} \\\\=40$

Now, we have been given that out of this 50% of rs 80 means out of rs 40, 25% has been spent.

Therefore, the remaining amount is given by

$80-\frac{40\times 25 }{100} \\\\=80-10\\=70$

Thus, Rs 70 has been left.

Answer 2

Given :

Total rupees = 80

First find out 50 % of 80


80 x 50/100 = 40

So , 50 % of 80 is Rs 40.


Now, find out 25 % of 40

40 x 25/100 = 10

So, 25% of 40 is 10


Total money = 80

Total spendings = 10.

Finding savings-

Savings = Total money - Total spendings

Savings = 80 - 10 = 70



$\bold{Answer: Savings \: = \: Rs \: 70}$
