Question

After spending 30% of her money, a lady has
70 left. How much had she first?​

Answer 1

Answer:₹100

Step-by-step explanation: Money left=₹70

Let the money she had originally be x.

So, when thirty percent of x is subtracted from x, we get 70.

This can be written as x-30x/100=70

=100x-30x/100=70

=70x=7000

=x=7000/70

=x=₹100

Hope it helps.
