Answer 2

Answer:

Pooja is deficient than Raj by 66.67%  or  approx  67%

Step-by-step explanation:

If Raj is 40% more efficient than Pooja.

Let efficient of Raj be x

Let efficient of Pooja be y

Raj is efficient than Pooja by

$\Rightarrow \dfrac{x-y}{x}\times 100=40\%$

$\Rightarrow 1-\dfrac{y}{x}=0.4$

$\Rightarrow \dfrac{y}{x}=0.6$

$\Rightarrow \dfrac{x}{y}=\dfrac{10}{6}$

Pooja is deficient than Raj by

$\Rightarrow \dfrac{y-x}{y}\times 100=e\%$

$1-\dfrac{x}{y}=e\%$

$1-\dfrac{10}{6}=e\%$

$\dfrac{4}{6}=e\%$

$\dfrac{2}{3}=e\%$

Hence, Poojs is deficient than Raj by 66.67%
