four concentric circles r given .the radius of 1st circle is x.next is 2x,then 3x and 4x. given that area b/w 2nd and 1st is A and 4th and 3rd circles being B.find ratio of A to B

Solution

area of first circle = pi*(x)^2 = pi*x^2
area of second circle = pi*(2x)^2 = 4*pi*x^2
area of third circle = pi*(3x)^2 = 9*pi*x^2
area of fourth circle = pi*(4x)^2 = 16*pi*x^2
area b/w 1st and 2nd circles = 3*pi*x^2
area b/w 3rd and 4th circles = 7*pi*x^2
so ratio = 3:7

(#M40000210) MICROSOFT QUESTION Keep an EYE

If you have two buckets, one with red paint and other with blue paint, and you take one cup from the blue bucket and pour it into the red bucket. Then you take one cup from the red bucket and pour it into the blue bucket. Which bucket has the higher ratio between red and blue? Prove it mathematically.

Solution

let volume of paint in bucket=10 liter
volume of cup = 1 liter
bucket A= red paint
Bucket B= Blue paint
after step 1=> Bucket A= 11 liter = 10 liter red + 1 liter blue
Bucket B= 9 liter blue

now 1 liter of bucket A= 1/11 liter blue and 10/11 red

after step 2=> Bucket A= 10 liter=100/11 red +10/11 blue
red/blue= 10/1

Bucket B= 10 liter
= 9 liter blue+1/11 blue +10/11 red
= 100/11 blue + 10/11 red .
red/blue = 1/10
so ratio of red/blue is (10/1) higher in first bucket of red paint than the ratio of red /blue (1/10) in second bucket
