There are 5 packages. The weight of 1st package is 500 kg and the weight of the 2nd package is 50% higher than the weight of 3rd package whose weight is 45% higher than the 1st package weight. The fourth package at 360 kgs is 60% lighter than the fifth package. Find the average weight of all the five packages.
A714.5 kgs
B798.3 kgs
C723.9 kgs
D712.6 kgs
Answer: Option A
Explanation:Weight of tst package = 500 kgs
Weight of 3rd package is 45% higher than the tst package.
i.e., 45 x 500/100 + 500 = 225 + 500 = 725 kgs.
2nd package is 50% higher than the weight of 3rd package
i.e., 50 x 725/100 * 725 = 1087.5 kgs
Weight of the 4th package is 360 kgs which is 60% lighter than the fifth p
ackage
Let the weight of 5th package be X.
Then the weight of 4th package = 360 kgs = X - 60X/100
360 kgs = X - 60X/100
40X/100 = 360
X=900
Therefore, the weight of 5th package = 900 kg.
Total of 5 packages = (500 + 1087.5 + 725 + 360 + 900) = 3572.5 kgs
Average= 3572.5/5 = 714.5
