Correct Answer: 74.16
Correct Answer: 48 km/hr
Correct Answer: 33 km/hr
Correct Answer: 80
Correct Answer: 9 sec
Explanation:
Relative speed = 68-8 = 60 km/hr = 60 X 5 / 18 m/s = 50/3 m/s
Total distance = 150 m
Time taken to pass a man running in same direction = 150 X 3/50 = 9 seconds
Correct Answer: 72
Correct Answer: 64.8
Correct Answer: 6 seconds
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.
