Question

Manisha's father has 5 mobile sets.
out of them 3 are out of order. What
percent of mobiles are out of order?​

Answer 1

Answer:

Step-by-step explanation:

let present age of Manisha= 'x' years

let present age of her father= 'y' years

According to the question-

1st case

x+y=50

=> x=50-y •••••••(1)

2nd case

(x-5)+(y-5)=24

=> x-5+y-5=24

=> x+y-10=24

=> x+y=24+10

=>x+y =34

Putting the value of 'x' from equation 1,we get:

50-y+y=34

=> 50=34 (because y will get cancelled)

and hence your question is wrong

Answer 2

Answer:

60%

Step-by-step explanation:

No. of mobile sets=5

No. of mobile sets which are out of order=3

Therefore,

Percentage of out of order sets=(3/5)*100

=3*20=60%
