Answer 2

Given that ,

An employee earns 2,00,000 in 10 months

We have to find :-

How much will he earns in 8 months.

In How many months will he earn Rs. 6,00,000.

Solution:-

First we will find Per month how much he earns

2,00,000 - 10 months

x rupees - 1 month

Do cross multiplication

2,00,000 × 1 = (10month s ) (xrupees)

2,00,000 = 10x Rupees

x = 2,00,000/10 Rupees

x = 20,000 Rupees

So, he earn per month 20,000 Rupees

a ) Per 8 months he earn = 20,000 × 8

He earns in 8 months = 1,6 0,000

b ) 1 month - 20,000Rs

x months - 6,00,000Rs

Do cross multiplication

6,00,000 × 1 = 20,000 × xmonths

6,00,000 = 20,000x

x = 6,00,000/20,000

x = 60/2

x = 30 months

He earns 6,00,000 Rs in 30 months
