Question

Alka spends 90% of the money that she received every month and save rupees 120 how much money does she get monthly

Answer 1

Hey mate
.
Here is your answer

.


Let the total money be x 

now money she spends = 90x/100

money she saves = 120

NOW

90x/100 + 120 = x 

x - 90x/100 = 120

10x/100 = 120 

x = 120 x 100/10 

x = 1200

she earns 1200

Hey buddy ❤

Hope this helps...

Step by step explanation ...

Percentage of money spent by Alka= 90%

Therefore, Percentage of money saved by Alka= (100-90)%
= 10%
Amount of money saved = Rs. 120

Let the total amount be 'x'

Therefore, 10% of x = Rs. 120

Or, 10/100 × x = Rs. 120

or, 10x/100 = Rs. 120

or, X = Rs. 100×120/10
= Rs. 1200

Have a nice day ...
