The value of $$x$$ where $$x$$ : $$2\frac{1}{3}$$ :: $$21$$ : $$50$$ is –
a) $$1\frac{1}{{49}}$$
b) $$1\frac{1}{{50}}$$
c) $$ \frac{{49}}{{50}}$$
d) $$\frac{{27}}{{50}}$$
Answer: c
Explanation:
$$\eqalign{
& = x:2\frac{1}{3}::21:50 \cr
& 50x = \frac{7}{3} \times 21 \cr
& 50x = 49 \cr
& x = \frac{{49}}{{50}} \cr} $$
