Question

A landlord owns 3 condominiums, a 1-bedroom condo, a 2-bedroom condo, and a 3-bedroom condo. The total rent she receives is $1240. She needs to make repairs on the condos, and it costs 10% of the 1-bedroom condo’s rent for its repairs, 20% of the 2-bedroom for its repairs, and 30% of the 3-bedroom condo’s rent for its repairs. The total repair bill was $276. The 3-bedroom condo’s rent is twice the 1-bedroom condo’s rent. How much is the rent for all three condos?

Answer 1

• 1 bedroom condo rent be x
• Three bedroom condo rent be 3x.

Total spent percentage=30+10=40%

Now

`\\ \sf\longmapsto 40\%\:of 1240`

`\\ \sf\longmapsto 0.40(1240)`

`\\ \sf\longmapsto 472`

Total rent for three condos

`\\ \sf\longmapsto 472+276=752`
