JNU SSS 2010 Question 35: Limits, continuity and differentiability

If the elasticity of f(x)f(x)f(x) with respect to xxx is 0⋅50\cdot50⋅5 (f(x)>0f(x) > 0f(x)>0 and x>0x > 0x>0), then the elasticity of f(x)/xf(x)/xf(x)/x with respect to xxx is

Plain-text version

If the elasticity of f(x) with respect to x is 0·5 (f(x) > 0 and x > 0), then the elasticity of f(x)/x with respect to x is (A) -0·5 (B) 0 (C) 0·5 (D) 1

Also written as: If the elasticity of f(x) with respect to x is 0*5 (f(x) > 0 and x > 0), then the elasticity of f(x)/x with respect to x is
