Musa contributes 8% of his annual income to a charity and yakubu contributes 5% of his income to the same charity.if Musa earns 80000 per month and yakubu earns 50000 per month.what is the sum of their annual contributes to the charity?

Answer 1

Musa earns 80000 * 12 = <<80000*12=960000>>960000 per year.
So, Musa contributes 960000 * (8 / 100) = <<960000*(8/100)=76800>>76800 to the charity each year.
And Yakubu contributes 50000 * 12 * (5 / 100) = <<50000*12*(5/100)=30000>>30000 to the charity per year.
Therefore, the sum of their annual contributes to the charity is 76800 + 30000 = <<76800+30000=106800>>106800. Answer: \boxed{106800}.
