Correct Answer: 6 seconds

Correct Answer: 64.8

Correct Answer: 72

Correct Answer: 580m

Correct Answer: 74.16

Correct Answer: 18

Explanation:

Let S.P. of 45 lemons be Rs. x.

 

Then, 80 : 40 = 120 : x or   x =  40 × 120 80= 60

 

For Rs.60, lemons sold = 45

 

For Rs.24, lemons sold  = 45 60 × 24= 18.

Correct Answer: 16

Explanation:

Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x. 

S.P. of x articles = Rs. 20. 

Profit = Rs. (20 - x). 

20 - x x * 100 = 25 

=> 2000 - 100x = 25x 

=> 125x=2000 

=> x=16

Correct Answer: 100%

Explanation:

Let the C.P be Rs.100 and S.P be Rs.x, Then
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x
New profit is (2x-100)
Now as per the given condition;
=> 3(x-100) = 2x-100
By solving, we get
x = 200
Then the Profit percent = (200-100)/100 = 100
Hence the profit percentage is 100%

Correct Answer: 21%

Explanation:

Gain % = 100 + c o m m o n g a i n % 2 100 - 100%           

 

           = 100 + 10 2 100 - 100

 

            = 21%

Correct Answer: 166.66%

Explanation:

Let the cost price of 1-liter pure milk be Re.1, then 

  6 l i t e r s ( m i l k ) ? C . P = R s . 6 2 l i t e r s ( w a t e r ) ? C . P = R s . 0 ? C P = R s . 6 o n l y

 

8 litre mixture  =>

SP =>  8 x 2 = Rs. 16

 

Profit % =  16 - 6 6 x 100 = 1000 6 = 166 . 66 %
