What is the ratio of the number of candidates failing the exam from City D to that of those failing the exam from City A ?

Answer:

Explanation:

Number of candidates failing from city D

= $\left(\frac{3}{4}\times2.27\times100000\right)$

= $\left(\frac{3}{4}\times\frac{227}{100}\times100000\right)$

= $\left(227\times750\right)$

Number of candidates failing from city A

= $\left(\frac{3}{10}\times1.25\times100000\right)$

= $\left(\frac{3}{10}\times\frac{125}{100}\times100000\right)$

= $\left(300\times125\right)$

Required ratio : $\left(\frac{227\times750}{300\times125}\right)$

= $\frac{227}{50}= 227:50$
