Answer 1

21.3%

Explanation:

Given that:

Money spent by Jodie for buying English reading books = 25% lesser than that of Claudia

and

Money spent by Gianna is 9% lesser than that of Claudia.

To find:

By what percent, Gianna spent more than Jodie ?

Solution:

Let the money spent by Claudia on her English books = 100

Now, as per question statement:

Money spent by Jodie = 100 -
`(9)/(100)* 100` = 75

Money spent by Gianna = 100 -
`(25)/(100)* 100` = 91

Now, to find the answer:

`\frac{\text{Difference between money spent by Gianna and Jodie}}{\text{Money spent by Jodie}}* 100`

`\Rightarrow (91-75)/(75)* 100\\\Rightarrow (16)/(75)* 100\\\Rightarrow \bold{21.3\%}`

Therefore, Gianna spent 21.3% more than the amount that was spent by Jodie.
