Answer 1

Answer: mohan's present age is 5 years

Step-by-step explanation:

let mohan's age be x years

let father's age be y years

let suresh's age be z years

given that,

x=1/6y-------------------------(1)

also after 10 years,     y+10=2(z+10)------------------------(2)

before 2 years, suresh was 8 years old ;

 z-2=8

z=8+2

z=10----------(3)

  substitute (3) in (2),       y+10=2(20)

   y=30-------------(4)

substitute (4) in (1);         x=1/6(30)

 x=5

ans: mohan's present age is 5 years
