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%.
