b)120
c)145
d)160
answer:a
ok this is s bit difficult to explain because i have not used formulas, just common sense.
Put it this way:as if you are weighting 100 cars. You know that 76 of those cars weight less than 154kg. And you know that 60% of the cars that weight more than 100kg weight more that 154kg....that gives you 24 cars that weight more that 154 kg. The other 40% are 16 cars.....76-16=60.....60 cars weght less than 100kg.
So the answer must be less than 100. The only naswer possible answwre is A.
Regards!
