Answer:
Marks age is 24.
Step-by-step explanation:
If Sunita's age is x then Mark's age = 4x/3 years.
In 12 years their ages will be (x + 12) and 4x/3 + 12.
So (x + 12) / (4x/3 + 12) = 5/6
6(x + 12) = 5(4x/3 + 12)
6x + 72 = 20x / 3 + 60
72 - 60 = 20x/3 - 6x Multiply through by 3:
216 - 180 = 20x - 18x
2x = 36
x = 18 = Sunita's age
So Mark's age is 18 * 4/3 = 24 years.
A=124
B=0.7x+75
124<0.7x+75
49<0.7x
70<x
