Alka spend 90% of the money that she receives every month and saves Rs . 120. how much money does the get monthly​

Answer»

Percentage of money Alka spends monthly = 90%

Then, percentage of money she saves monthly = 100%-90% = 10%

AMOUNT of money she saves monthly = ₹120

Let the total money she earns monthly be x.

By the statement,

10%of x = ₹120

=> 10x/100 = ₹120

=> x/10 = ₹120

=> x = ₹(120×10)

=> x = ₹1200

Therefore, the amount of money she earns monthly = x = ₹1200

Answer: Alka earns 1200 EVERY month.
