Question

Rohan's mother is 20 years older than him. The product of their ages (in years) 5 years

from now will be 300 years. Find Rohan's present age.​

Answer 1

Answer:

Step-by-step explanation:

Rohan's present age= x

Rohan's mom's age = x+20

5 years after:

Rohan's age= x+5

Rohan's mom's age= x+20+5= x+25

Condition given=

(x+5)*(x+25)=300

x^2+25x+5x+125=300

x^2+30x+125=300

x^2 + 30x = 300-125

x^2 +30x=  175

x(x+30)=175

x^2=145

x=12
