The ratio of two numbers is 5 : 4 .If 40 % of the first number is 12 , then what would be 50 % of the second number ? ​

Answer 1

There is a ratio of 5 :4 between two numbers.

Let the rationale between two numbers be x. Thus two numbers are 5x and 4x.

If 40 percent of the first number is 12

5x × 40/100 = 12

200x/100 =12

2x = 12

x = 6

Thus first number 5x = 5 × 6 = 30

Second number 4x = 4 × 6 = 24

what would be the 50 percent of the second number

Now 50% of 24

= 24 × 50 /100

= 24 × 1/2

=24/2

= 12

50% of second number is 12

Answer 50% of second number is 12

Answer 2

Answer:

12

Step-by-step explanation:

Let the first no. be x

let the second no. be y

first no. =x*40/100=12

40x/100=12

40x=100*12

x=30

since their ratio is 5:4 then

x/y=5/4

30/y=5/4

y=24

=24*50/100=?

12

50% of the second no. is 12
