Isha is 5 years younger than her brother. After 4 years, their ages will be in the ratio 2:3, find their present ages.

Isha is 6 years old and her brother is 11 years old.

Step-by-step explanation:

x = Isha's age

y = Brother's age

y-5=x

(x+4)/(y+4) = 2/3

x = 6, y = 11

Isha is 6 years old and her brother is 11 years.

two data sets with the same median will not have the same varaibility

step-by-step explanation:

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
