Correct Answer: 64.8
Correct Answer: 72
Correct Answer: 580m
Correct Answer: 74.16
Correct Answer: 48 km/hr
Correct Answer: 5%
Explanation:
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
Gain =(80/1600*100) % = 5%
Correct Answer: 18
Explanation:
Let S.P. of 45 lemons be Rs. x.
Then, 80 : 40 = 120 : x or x = = 60
For Rs.60, lemons sold = 45
For Rs.24, lemons sold = = 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).
=> 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 % = %
=
= 21%
