Question

A torch and a battery cost 2.50 altogether. the torch costs 1.50 more than the battery. what fraction of the total price is the torch? give your answer in its simplest form.

Answer 1

Answer:

4/5

Step-by-step explanation:

let x= torch

let y= battery

given

x+ y = 2.5-----(1)

&

x= 1.5+ y

x-y=1.5-----(2)

by solving one and 2 we get

x= 2

and y= 0.5

so proportion is 2/2.5

= 4/5

Answer 2

Answer:

4/5 fraction of the total price is the torch

Step-by-step explanation:

Let the cost of battery be a and cost of torch be (a+1.50)

ATQ, a+a+1.50=2.50

or, 2a=2.50-1.50

or, a=1/2

or, a=0.50

So, cost of battery=0.50 and cost of torch=0.50+1.50=2

Now,

fraction of the total price is the torch=2/2.50

=4/5
