Question

The difference between two number is 8 and their ratio is 5:1 which of the following is the smaller number

Answer 1

Step-by-step explanation:

Let bigger no. be xand smmaller be y

Now, x-y = 8 ---- (1)

ratio x/y = 5:1

take y to next to 5 it is 5y

put 5y in (1)

5y - y = 8

4y = 8

y = 8/4

y = 2 ------(2)

x - y = 8

put (2) y=2

x - 2 = 8

x = 8 + 2

x = 10

smaller no. = y = 2
