Number of cellular phones (both Nokia and Samsung) sold by store Q in October
= 11200 × $$\frac{10}{100}$$
= 1120
∵ Number of cellular phones (both Nokia and Samsung) sold by store Q in November
= 1120 × $$\frac{115}{100}$$
= 1288
Number of cellular phones (both Nokia and Samsung) sold by store T in October
= 11200 × $$\frac{20}{100}$$
= 2240
∵ Number of cellular phones (both Nokia and Samsung) sold by store T in November
= 2240 × $$\frac{105}{100}$$
= 2352
∵ Total number of cellular phones (both Nokia and Samsung) sold by Q and T together in November
= 1288 + 2352
= 3640
