Question
When 60 is subtracted from 60% of a number to give 60, the number is
Options
60
100
150
200
Solution
200
Explanation;
Hint:
Let the number be ‘x’
60% of the number is `60/100 xx x = (60x)/100`
Given that when 60 is subtracted from 60%, we get 60
i.e `60/100x - 60` = 60
∴ `60/100x` = 60 + 60
∴ `60/100x` = 120
∴ x = `(120 xx 100)/60` = 200
