\(\frac{E*10*30}{100}\)= \(\frac{E}{2}*\frac{40*T}{200}\)
3=\(\frac{1}{10}*T\)
T=30
3=\(\frac{1}{10}*T\)

Method 1;
time per article ; 100/30 ; 3.33
time per men ; 3.33/10 ; .33
effici
.33*40 = 13.33
given efficiency is half ; 13.33/2
200*2 /13.3 = 30
IMO C
Method 2
m1*t1/w1= m2*t2/w2
10*30/100 = 1/2 * 40*t2/200
t2 = 30 mins
