(1) $6: 5$

(2) $5: 6$

(3) $11: 6$

(4) $16: 15$

(5) $20: 11$

Show Answer

Correct Answer: (4)

Solution: (4)

For company $X$,

$50=\frac{I-E_{1}}{E_{1}} \times 100$

$\Rightarrow 50 E_{1}=100 I-100 E_{1}$

$\Rightarrow 150 E_{1}=100 I$

For company Y,

$60=\frac{I-E_{2}}{E_{2}} \times 100$

$\Rightarrow 60 E_{2}=100 I-100 E_{2}$

$\Rightarrow 160 E_{2}=100 I$

$\therefore 150 E_{1}=160 E_{2}$

$\Rightarrow \frac{E_{1}}{E_{2}}=\frac{160}{150}=16: 15$
