A) 4
B) 1
C) 2
D) 3
Correct Answer: A
Solution :
as \[x=\frac{R(100-\ell )}{\ell }\] For [a] \[x=\frac{1000\times (100-60)}{40}\approx 667\] for [b] \[x=\frac{100\times (100-13)}{13}\approx 669\] for [c] \[x=\frac{10\times (100-1.5)}{98.5}\approx 656\] for [d] \[x=\frac{1\times (100-1)}{1}\approx 95\] So option [d] is completely different hence correct Ans.
