Answer 1

UNITARY METHOD

NO. of computer for 6 children:- 3

No. of computer for 1 child:- 3/6= 1/2

No. of computers for 24 students:- 24×1/2

= 12 computers

Answer 2

Answer:

Using Unitary Method, we have

6 students require 3 computers

∴ 1 student will require = 36 computers

∴ 24 students will require = 36 x 24 computers

= 3 × 4 computers = 12 computers

Hence the number of computers required = 12.
