A Google-owned IT industry has started a bus service for its employees. The number of passengers a bus can carry is 45 and the average weight of all the employees must not succeed 64/kg. One a given day, it is noted that fewer persons have boarded the bus and thus increases the average weight by 8/kg. Find the number of lesser persons boarded that day. (Also, the total weight must be same throughout).1). 52). 23). 34). 1

Answer»

The total weight of all the employees = NUMBER of employees × average weight

Total weight = 45 × 64 = 2880 kg

Given that, fewer employees have boarded the BUS,

Let the number of employees on that DAY be ‘x’

As the total weight MUST REMAIN the same,

New increased average weight = 72/kg

⇒ x × 72 = 2880

⇒ x = 40

∴ 5 lesser persons have boarded the bus that day.
