Answer 1

11=1100
1=100
4= 100×4=400 will be the answer

Answer 2

• We are given that total A,B, C contract a work for Rs.1100.
• We have to find C's share out of this Rs. 1100.

• Since A and B are together doing 7/11 of the work, i.e out of a portion of 1, 7/11th portion of work is done by A & B.

• Since work done by A and B is 7/11, we can say that work of C will be :

       = 1- 7/11

       = 4/11

• So now we have calculated how much portion of work C has done.

• Now we will calculate C's share, from total amount of Rs.1100.

• C's share will be 4/11 th of total share :

        = 4/11 * Rs.1100

        = Rs. 400

• So C's share is Rs 400.
