Tonya is twice kevin's age. in three years, tonya will be 17. and in another three years, uncle rob will be three times tonya’s age.
how old is kevin and uncle bob

17-3 = 14 ( Tonya's age now)

14/2 = 7 ( Kevin's age)

14*3 = 42 ( Uncle Bob's age)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

1; 35 is the ratio
