Show answer & explanation
Correct answer: D
Let the number be x.
60% of x is 0.6x.
According to the problem, 0.6x - 60 = 60.
Add 60 to both sides: 0.6x = 120.
Divide both sides by 0.6: x = 120 / 0.6 = 200.
Therefore, the number is 200.
हिन्दी उत्तर:
माना संख्या x है।
x का 60% = 0.6x
प्रश्नानुसार, 0.6x - 60 = 60
दोनों तरफ 60 जोड़ने पर: 0.6x = 120
दोनों तरफ 0.6 से भाग देने पर: x = 120 / 0.6 = 200
इसलिए, संख्या 200 है।
