Question

In a computer lab , there are 3 computers for every 6 students .How many computers will be needed for 24 students?

Answer 1

Since, every 6 students need 3 computers.
Hence, every 1 student needs 3 ÷6 computers.
Hence, every 24 students need (3 ÷ 6) x 34 = 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.
