Question 1.

Make necessary reasonable assumptions and answer the questions below: Class 7

(a) If a single sheet of paper weighs 5 grams, could you lift one lakh sheets of paper together at the same time?

Solution:

Weight of one lakh sheets = 5 × 100000 = 500000 grams = 500 kg.

So, I cannot lift the sheets.

(b) If 250 babies are born every minute across the world, will a million babies be born in a day?

Solution:

Number of babies born in a day = 250 × 60 × 24 = 360000, which is less than one million.

So, one million babies will not be born in a day.

(c) Can you count 1 million coins in a day? Assume you can count 1 coin every second.

Solution:

Number of coins counted in a day = 1 × 60 × 60 × 24 = 86400.

So, 1 million coins cannot be counted in a day.
