computers will be needed for 24 students?

Answer 1

Answer:

for 24 students we need 12 computers

Answer 2

Answer:

Given:

Population of Rajasthan = 570 lakhs

Population of UP = 1660 lakhs

Area of Rajasthan = 3 lakh km2

Area of UP = 2 lakh km2

(i) Number of people per km2 of Rajasthan 5

=570 lakhs 3 lakh km2

= 190 per km2

Number of people in UP = 1660 lakhs

Area of UP = 2 lakh km2

Number of people per km2 of UP

= =1660 lakhs 2 lakh km2=830 per km2

Since 190 per km2< 830 per km2

(ii) Rajasthan is less populated state.

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.
