Question

the difference between present ages of a man and son is 25. If the product of their ages 10 years back was 350 find the present age of father and son​

Answer 1

Step-by-step explanation:

let man's age be x and son be y.

x-y=25 (x-10)(y-10)=350

xy-10y-10x+100=350

xy -10y-10x=250

x=25+y 25y+y2-10y-250-10y =250

y2 +5y=500

:. x=45.y=20
