Question

A women invests 3750 in shares which is 25% of her monthly income what's her monthly income

Answer 1

Let the monthly income be Rs x.

25/100*x=3750

x=3750*100/25

x=15000

Monthly income=Rs 15000

Answer 2

The share 3750 is equivalent to the 25%
Therefore we need to compare the percentage and the share to get the answer as below:
Let her income be x
25% of x = 3750
25/700*x= 3750
25x/100 = 3750
Here you multiply both sides by the fraction to eliminate the fraction:
25x = 3750*100
25x = 375000
25x/25 = 375000/25
X = 15000
Therefore, her salary was 15000
