Question

In a class of 80 students, 20 are females. What is the ratio of males to females?
( )1:3
( )3:1
(x)1:4 ← Wrong answer
( )2:3

Answer 1

Answer:

3:1

Step-by-step explanation:

Number of males = 80-20 = 60

Number of females = 20

ration of males to females

= 60/20

= 3 or 3:1

Answer 2

$\underline{\underline{\mathfrak{Answer}}}$

Let the number of boys be x

From the question,we know that there are 20 students out of 80 are girls

Now,

$\sf{x + 20 = 80} \\ \\ \implies \: \sf{x = 80 - 20} \\ \\ \huge{\sf{ \implies \: x = 60}}$

Implies,there are 60 boys

The girls and boys ratio would be

60:20

=60/20

=3:1

The correct option is (2)
