Question

- A number when increased by
87 1/2%, it becomes 89 1/3% of
another number. Find the ratio of
both numbers?
a) 12:7 b) 7:4
c) 5:3
d) 3:1
e) 9:4​

Answer 1

Answer:

e) 9:4

Step-by-step explanation:

Let the first number be denoted as x

And the second one as y

Then, when the first number is increased by 87.5% it becomes:

x*1.875= 1.875x

87 1/3% of the second number is

(87 1/3)/100 *y= 131/150 *y

= 131/150 y

The relationship between these two is:

1.875x = 131/150 y

x= (131/150 ÷1.875)y

x=(524/1125) y

1125x= 524y

Therefore the ratio of

x:y = 1125:524

Which can be expressed as 8.5877:4

Ans= e) 9:4
