Answer 2

Answer:

65 kg

Step-by-step explanation:

$\bold{\underline{\underline{Method\:1)}}}$

Average weight of 5 person is increased by 1 kg.

⇒ (5 × 1) kg

⇒ 5 kg

Another man weighs 60 kg is replaced by new man.

We have to find the weight of the new man.

To find the weight of the new man. We have to add the weight of the first man and weight of the another man after replacement.

i.e.

⇒ (60 + 5) kg

⇒ 65 kg

∴ 65 kg is the weight of the new man.

$\bold{\underline{\underline{Method \:2)}}}$

Let take -

• weight of one man = 60 kg

Average weight of 5 person is increased by 1 kg.

Means, weight of each person is increased by 1 kg.

So, sum of weight of one man and product of 5 persons weight.

i.e.

⇒ 60 + (5 × 1)

⇒ 60 + 5

⇒ 65 kg

∴ 65 kg is the weight of the new man.
