The number of mobile phones sold of Company A during July is approximately what percent of the number of mobile phones sold of Company A during December?


A) 110

B) 140

C) 150

D) 105

E) 130

Answer:

Option E

Explanation:

No. of mobile phones sold by A during July

= $\frac{17}{100}\times\frac{8}{15}\times45000$

= 4080

No. of mobile phones sold by A during December

= $\frac{16}{100}\times\frac{7}{16}\times45000$

= 3150

Let 4080 = x% of 3150 Then,

= $\frac{x}{100}\times3150 = 4080$

x = $\frac{4080\times2}{63}$ = 129.5 = 130

Required percentage = 130%.
