The average weight of five persons sitting in a boat is 38 kg. The average weight of the boat and the persons sitting in the boat is 52 kg. What is the weight of the boat ?
Answer & Solution
Correct Answer:
Option
B
Let the five persons be A, B, C, D, E
According to the question,
= $$\frac{A + B + C + D + E}{5}$$ = 38 kg
= A + B + C + D + E = 190 kg.....(i)
$$\frac{{5\,{\text{persons}} + {\text{Boat}}}}{6} = 52$$
5 persons + Boat = 312 kg.....(ii)
∴ Boat's weight = 312 - 190 = 122 kg
According to the question,
= $$\frac{A + B + C + D + E}{5}$$ = 38 kg
= A + B + C + D + E = 190 kg.....(i)
$$\frac{{5\,{\text{persons}} + {\text{Boat}}}}{6} = 52$$
5 persons + Boat = 312 kg.....(ii)
∴ Boat's weight = 312 - 190 = 122 kg
