d)2000
Answers
Answer:
c 1800
Step-by-step explanation:
total number of people = 3000
number of male = 2/5 of 3000
therefore no of males = 1200
number of female = number of people - number of male
= 3000- 1200
=> 1800 ans
There are 1800 females in that village.
∴ Ans: c) 1800
Step-by-step explanation:
It is given that,
Total number People in the village = 3000
Out of 3000 people 2/5 are male.
Hence, the number of male members = (3000 × 2/5)
= (600 × 2)
= 1200
∴ There are 1200 male members.
∴ The number of female in that village = (3000-1200)
= 1800
∴ There are 1800 female members.
Hence, option. c) 1800 is the correct answer.

It can be done except calculating the number of males by fractional method, let's check that process as well_
Let the total number of member in the village be 1 part
The number of male is 2/5 part
∴ The number of female is (1-2/5) part
= (5-2)/5 part [∵ The L.C.M. is 5]
= 3/5 part
We know that,
1 part = 3000 people
Hence, 3/5 part = (3000× 3/5) people
= (600×3) people
= 1800 people
Hence, the number of female in that village is 1800.
