Question

ratio of two nos is 5:7 if 40 is subtrain from each no. then two ratios will be 17:27 find thease nos

Answer 1

Let the two numbers be x and y,

Since the ratio be 5x and 7x

According to the question, 40 is subtracted from the given numbers then the ratio becomes 17:27.

$\frac{5x-40}{7x-40}=\frac{17}{27}$

Cross multiplying in the given equation,

$27(5x-40)=17(7x-40)$

$135x-1080=119x-680$

$16x=400$

x=25

First number =$5x=5 \times 25= 125$

Other number =7x= 175
