Solution



S8. Ans.(c)
Sol. Polyester = (10000 – 5600) + (10000 – 6000) + (9200 – 5600) + (10400 – 5600) 
= 16800 m.
Nylon = (5600 – 2000) + (6000 – 3200) + (5600 – 3200) + (5600 – 2400) 
= 12000 m 
Ratio = 7 : 5 

S9. Ans.(b)
Sol. Production of Nylon in Jan = 3600
Production of Nylon in Feb = 2800 
Production of Nylon in April = 3200 
Average = 9600/3=3200 mt. 

S10. Ans.(a)
Sol. In Feb, increment = 1200/2000×100=60%
In march, increment = 0%
In April decrement = 800/3200×100=25%
