allery1200 ची रक्कम दोन व्यक्तींमध्ये 3 : 5 या गुणोत्तरात विभागली जाते. मोठा वाटा किती आहे:
A450
B750
C600
D700
Answer & Solution
Correct answer: B. 750
1. 3 : 5 हे गुणोत्तर या रकमेचे 3 + 5 = 8 समान भागांमध्ये विभाजन करते.
2. एका भागाची किंमत 1200 / 8 = 150 आहे.
3. मोठा वाटा 5 भाग घेतो.
4. त्यामुळे तो 5 x 150 = 750 आहे.
5. पडताळा म्हणून, लहान वाटा 3 x 150 = 450 आहे, आणि 750 + 450 = 1200.
