Arrange the number a = $$\frac{7}{{10}},$$ b = $$\frac{5}{8},$$ c = $$\frac{2}{3}$$ in descending order = ?
A. a > b > c
B. a > c > b
C. b > c > a
D. c > b > a
Answer: Option B
Solution(By Examveda Team)
$$\eqalign{ & a = \frac{{7 \times 24}}{{10 \times 24}} = \frac{{168}}{{240}} \cr & b = \frac{{5 \times 30}}{{8 \times 30}} = \frac{{150}}{{240}} \cr & c = \frac{{2 \times 80}}{{3 \times 80}} = \frac{{160}}{{240}} \cr & {\text{The descending order}} \cr & {\text{ = }}a > c > b \cr} $$Related Questions on Ratio

A. 2 : 1
B. 14 : 3
C. 7 : 2
D. 1 : 2
If $$\frac{2}{3}$$ of A=75% of B = 0.6 of C, then A : B : C is
