AFCAT II 2014 Solved Paper

Area of towel = l×b =100 cm × 50cm = 5000cm2
Now, length decreased by 20% and breadth decreasedby 10%
l = 100 – 20% of 100 = 80cm
b = 50 – 10% of 50 = 45cm
New area = l × b = 80cm × 45cm = 3600cm2
Change in area =(5000–3600)cm2=1400cm2
% change in area = ‌‌

1400

5000

×100=28%
