Question

if radha had rs.500 left after spending 50% of her money how much dis she had in the beginning ​

Answer 1

Rs. 1000

let the initial money be x rs. where x is not equal to 0.

then, ATP, we can write that:

x -50% of x = 500

or, x - ( 50/100) × x = 500

or, x - x/2 = 500

or,( 2x - x)/ 2 = 500

or, x /2 = 500

or, x = 500 × 2

or, x = 1000

thats the mathematical proof

I hope it helps
