x = 17264 - 17630

x = -366

Answer 2

Dear Student,

◆ Answer -

Wage of worker who had left = -566 Rs (practically impossible).

● Explanation -

Wage of all 216 workers is 216×79 = Rs. 17064.

Let x be wage of 1 worker who had left.

Wage of the remaining 216-1 = 215 workers is Rs. 82.

Wage of 215 workers is 215×82 = Rs. 17630.

Wage of worker who had left is 17064-17630 = -566 Rs.

Hence, our answer is -566 Rs (which is practically impossible but hey that's what your data says).

Thanks dear. Hope this helps you..
