Answer 2

SOLUTION

TO CHOOSE THE CORRECT OPTION

The average weight of 10 passengers in a boat is 56 kg. If the average weight of a boat along with the boatman increases by 1 kg, what will be the weight of the boatman

1. 57 kg

2. 61 kg

3. 68 kg

4. 67 kg

EVALUATION

Here it is given that the average weight of 10 passengers in a boat is 56 kg.

So sum of the weight of 10 passengers in the boat

= ( 10 × 56 ) kg

= 560 kg

Now it is given that the average weight of a boat along with the boatman increases by 1 kg

So Here number of passenger along with the boatman

= 10 + 1

= 11

So sum of the weight of passenger along with the boatman

= ( 11 × 57 ) kg

= 627 kg

Hence the weight of the boatman

= 627 kg - 560 kg

= 67 kg

FINAL ANSWER

Hence the correct option is 4. 67 kg
