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
