alleryएक दुकान 20% सूट देते. 250 छापील किंमत असलेल्या एका बॅगेची विक्री किंमत आहे:
A180
B210
C230
D200
Answer & Solution
Correct answer: D. 200
1. 20 टक्के सूट म्हणजे ग्राहक छापील किमतीच्या 80 टक्के रक्कम देतो.
2. येथे छापील किंमत 250 आहे.
3. म्हणून विक्री किंमत 80 / 100 x 250 आहे.
4. म्हणजेच ती 200 आहे.
5. दुसऱ्या पद्धतीने पडताळणी केल्यास, सूट 20 / 100 x 250 = 50 आहे, आणि 250 - 50 = 200.
