After 1st year 6400-25%=4800
After 2nd Year 4800-25%=3600

tuka81: can you explain me more?
aryan7274: yes
aryan7274: At starting 6400 labourers are there.Then after first year 20%of 6400 =1280 labourers left so only 5120 labourers left.Then after 2nd year again 20% of the labourers left after first year left which means 20% of 5120 which is1024 then after 2nd year only 4096 labourers were left
aryan7274: correction in place of 20% ot should be 25%
aryan7274: 25% of 6400=1600. After 1st year 6400-1600=4800 labourers left. then after 2nd year 25%of 4800 =1200 labourers left so only 3600 labourers were still working

3600 labourers will be left after two years

Step-by-step explanation:

Number of labors initially = 6400

25% labourers are to be discontinued every year

Number of labors after 1 year =6400-25\% \times 6400 = 6400-0.25(6400)=4800

Number of labors after 2 years =4800-25\% \times 4800 = 4800-0.25(4800)=3600

Hence 3600 labourers will be left after two years
