Mrs Sogiba is catering for her son's birthday party. She has invited some of her son's friends to the
party. The number of friends is a composite multiple
of her son's age on his birthday. She has baked
48 cupcakes and each child will receive exactly the
same number of cupcakes. Use your knowledge of
multiples and factors to find out how old her son
will be on his birthday.​

Step-by-step explanation:

Uhhh cat too long

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.
