The manager of a weaving factory estimates that if 10 machines run at 100% efficiency for 8 hours, they will produce 1450 meters of cloth. Due to some technical problems, 4 machines run of 95% efficiency and the remaining 6 at 90% efficiency. How many meters of cloth can these machines produce in 8 hours?

Answer:
2682.5metre
Step-by-step explanation:
Cloth machine can produce at full efficiency=1450m
efficiency of four machine=95%
=95/100×1450m
=1377.5m
efficiency of 6 other machine=90%
=90/100×1450
=1305m
total cloth made=1377.5m+1305
=2682.5m
