Slot -2 – Quantitative Aptitude – Arithmetic – Ratios – The scores of Amal and Bimal in

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?

a) 8 : 5
b) 3 : 2
c) 4 : 3
d) 5 : 4

Answer: c) 4 : 3

Solution: let their scores were 11x and 14x and it increase by n then
(11x+n)/(14x+n)=47/56
616x+56n=658x+47n
42x=9n
n = 42x/9
So Bimal’s new score = 14x + 42x/9 = 168x/9
So required ratio = (168x/9)/14x = 4∶ 3
