A number whose one fifth part is increased by 4 is equal to its one fourth part diminished by 16, then the number is:
120
115
400
390
The correct answer is Option (3) → 400
Let the number be x Given: x/5 + 4 = x/4 − 16 Multiply both sides by 20: 4x + 80 = 5x − 320 80 + 320 = 5x − 4x 400 = x Hence, the number is 400.
