Use of Large Numbers in Daily Life Situations

Use of Large Numbers in Daily Life Situations

We know to apply four basic operations on numbers. We will see a few more examples which deal with the four operations such as addition, subtraction, multiplication and division.

Example 1.5

In an exhibition, the number of tickets sold on the first, second, third and fourth days are 1,10,000,  75,060,  25,700 and 30,606 respectively. Find the total number of tickets sold on all the 4 days.

Solution

Number of tickets sold on the first day      = 1,10,000

Number of tickets sold on the second day  = 75,060

Number of tickets sold on the third day    = 25,700

Number of tickets sold on the fourth day  = 30,606

                                                                      = 2,41,366

Adding all the above, the total number of  tickets sold on all the 4 days                    = 2,41,366

Example 1.6

In a year, a whole-sale paper firm sold 6,25,600 notebooks out of 7,50,000 notebooks.

Find the number of notebooks left unsold.

Solution

Number of notebooks in the store = 7,50,000

Number of notebooks sold = 6,25,600

Number of notebooks unsold = 1,24,400

 Example 1.7

In a mobile store, the number of mobiles sold during a month is 1250. Assuming that the same number of mobiles are sold every month, find the number of mobiles sold in 2 years.

Solution

Number of mobiles sold in 1 month = 1250

1 year = 12 months

2 years = 2 × 12

= 24 months

Number of mobiles sold in 24 months = 1250 × 24= 30,000

Number of mobiles sold in 2 years = 30,000

Example 1.8

If ₹ 10,00,000 was distributed in a Government scheme to 500 women in the Self Help Groups, then find the amount given to each woman.

Solution

Amount to be given to 500 women = ₹ 10,00,000

Amount given to each woman = 10,00,000 ÷ 500 = ₹ 2000

Each woman in the Self Help Group was given ₹ 2000.
