C2 : 7

D7 : 2

Answer:

A. 4 : 49

Read Explanation:

നമുക്ക് ( a : b = 2 : 7 ) എന്ന് കൊടുത്തിട്ടുണ്ട്.

അപ്പോൾ,
ab=27,ba=72\frac{a}{b} = \frac{2}{7}, \quad \frac{b}{a} = \frac{7}{2}

ഇപ്പോൾ ratio:
ab:ba=27:72\frac{a}{b} : \frac{b}{a} = \frac{2}{7} : \frac{7}{2}

അതിനാൽ ratio:
4 : 49

ഉത്തരം: 4 : 49
