Total wage of 23 labourers in the initial group = 23 × 460 = Rs. 10580 New average wage of the group = 460 + 40 = Rs. 500 New number of labourers in the group = 23 – 4 + 2 = 21 So, according to the question, 10580 – 4 × 350 + 2K = 500 × 21 Or, 10580 – 1400 + 2K = 10500 Or, 9180 + 2K = 10500 Or, 2K = 10500 – 9180 = 1320 Or, K = (1320/2) = 660
