Neco 2018 Commerce Question 42

A company runs an advertising campaign using TV ads, radio spots and social‑media posts. The total cost of the campaign is \\(\text{₦}2{,}250{,}000\\). Each TV ad costs \\(\text{₦}150{,}000\\), each radio spot costs \\(\text{₦}30{,}000\\) and each social‑media post costs \\(\text{₦}5{,}000\\). The campaign must have twice as many TV ads as radio spots, and the number of social‑media posts must be three times the total number of TV and radio ads combined. Determine how many of each type of advertisement are used, and compute the total reach if each TV ad reaches 120{,}000 people, each radio spot reaches 25{,}000 people and each social‑media post reaches 8{,}000 people.
