# CAT 2018 Quant Questions

Question:
The scores of Amal and Bimal in an examination are in the ratio 11 : 14. After an appeal, their scores increase by the same amount and their new scores are in the ratio 47 : 56. The ratio of Bimal’s new score to that of his original score is

 5 : 4 8 : 5 4 : 3 3 : 2

Let the score of Amal and Bimal be 11k and 14k

Let the scores be increased by x

So, after increment, Amal's score = 11k + x and Bimal's score = 14k + x

According to the question,

$\frac{{{\rm{11k + x}}}}{{{\rm{14k + x}}}}$ = $\frac{{47}}{{56}}$

On solving, we get x = $\frac{{42}}{9}$k

Ratio of Bimal's new score to his original score

= $\frac{{{\rm{14k + x}}}}{{{\rm{14k}}}}$

=$\frac{{14k + \frac{{42k}}{9}}}{{14k}}$

=$\frac{{{\rm{168k}}}}{{{\rm{14*9k}}}}$

=$\frac{4}{3}$

Hence, option A is the correct answer.
