A) 89
B) 98
C) 102
D) 142​

Answer 1

Answer:

34

Step-by-step explanation:

finished work = 2/5

remaining work = 1-(2/5)

= 3/5

From the above formula

(m1 x t1/w1) = (m2 x t2/w2)

[(34 x 8 x 9)/(2/5)] = [(M x 6 x 9)/(3/5)]

34×8×9×(3/5) = M×6×9×(2/5)

7344 = M×108

M = 7344/108

so, M = 68 men

 

Number of men to be added to finish the work = 68-34 = 34 men.
