Answer 2

Answer:

3 four seater and 4 nine seater are required.

Step-by-step explanation:

Multiples of 4 :

$4 \times 1 =4$

$4 \times 2 =8$

$4 \times 3 =12$

$4 \times 4 =16$

$4 \times 5 =20$

$4 \times 6 =24$

$4 \times 7 =28$

$4 \times 8 =32$

$4 \times 9 =36$

$4 \times 10 =40$

Multiples of 9

$9 \times 1 =9$

$9 \times 2=18$

$9 \times 3 =27$

$9 \times 4 =36$

$9 \times 5 =45$

$9 \times 6 =54$

$9 \times 7 =63$

$9 \times 8 =72$

$9 \times 9=81$

$9 \times 10 =90$

12(multiple of 4)+36(multiples of 9 )=48

So, 3 four seater and 4 nine seater are required.
