Question

the ratio of two number is 5:6.if 40% of the first number is 12,what will be 50% of the second number?

Answer 1

Answer:

18

Step-by-step explanation:

let first number be y

so, 40 % of y = 12

40y/100 = 12

so, y = 1200/40 = 30

let second number be z.

so, y:z = 5:6

=> 30/z = 5/6

so, z = (30×6)/5 = 36

Now,

50% of z = 50% of 36 = (50×36)/100

= 18
