Correct answer
25
Why this answer is correct
For shop B; let, number of cameras sold be x : \(\frac{40}{100}× x=320.\)
x = 800.
number of printers sold = 220 × 2 = 440.
let, number of speakers sold be y : \(\frac{10}{7}=\frac{800}{y}\)
y = 560.
reqd percentage = \(\frac{1000 - (560 + 440)}{800}\times100= \frac{200}{800}\times100 =25\)%
