The average weight of 15 iron bars is 1000 kg. If the heaviest iron bar is removed, the average weight is reduced by 5 kg. Find the weight in kg of the heaviest iron bar.
A
1170kg
B
1270kg
C
1070kg
D
1370kg
Verified Correct Answer: C.
Step-by-Step Mathematical Solution
Total weight = 15 × 1000 = 15000 kg.
New average = 1000 - 5 = 995 kg.
Total for 14 bars = 14 × 995 = 13930 kg.
Heaviest = 15000 - 13930 = 1070 kg.
