number?
(a) 83.3
(b) 89.3
(c) 102.3
(d) 108.3
(e) 110.3

Answer 1

d

Explanation:

Let the number be 'x'.

First find x and then find 130% of x.

30% of x = 25

`\sf (30)/(100)*x = 25`

`\sf x = 25*(100)/(30)\\\\ x = (250)/(3)\\\\`

Now, find 130% of x

130% of x =
`\sf (130)/(100)*(250)/(3)\\\\`

`\sf = (325)/(3)\\\\ = 108.3`
