Concept
Multiplication means finding the product of two numbers. The number obtained after multpliying the numbers is known as product.
Given
A can alone do the work in 12 days and B can alone do in 8 days and they have received Rs.4800 for the work.
To find
The share of work if B leaves the work after 2 days.
Explanation
Suppose work contains 100 questions.
In 1 day questions that A can alone do=100/12
=8.33
In 1 day questions that B can alone do=100/8
=12.5
Now take the situation in wich A and B work together.
In 2 day questions that A does=8.33*2=16.33
In 2 day questions that B does=12.5*2=25
Payment will receive for 100 questions so the payment of 1 question=4800/100
=Rs 48.
Share of B=Payment of 1 question*Questions done by B in 2 days
=48*25
=Rs.1200
Hence the share of B is Rs.1200.
