A,B,C contract a work for 1020.together A and B are supposed to do 9/17 of work.how much C get?

ans 480rs

answer is correct

sir could you please explain this problem

(1-9/17)1020 = 8/17 * 1020 = 480

To determine how much C gets, we first need to find out how much work A and B do together.

Given that A and B are expected to do 9/17 of the work, we can set up the equation:

A + B = 9/17

Next, we can find the proportion of work C is expected to do by subtracting the combined work of A and B from the total work required.

So, C's work can be calculated as:

C = 1 - (A + B)

Now, to calculate the value of C, we need to substitute the given value of A and B. Given that A and B are contracted to complete 1020 units of work, we can rewrite the equation as:

C = 1 - (1020 * (9/17))

Simplifying the expression inside the parentheses:

C = 1 - (9180/17)

To subtract a fraction from 1, we need to find a common denominator. In this case, it is 17, as both the numerator and denominator in the fractional part have a denominator of 17:

C = (17/17) - (9180/17)

Subtracting the fractions:

C = (17 - 9180) / 17

Simplifying the numerator:

C = (-9163) / 17

Finally, dividing the numerator by the denominator:

C ≈ -539.59
