Sum of two numbers is 80. Greater number exceeds by 5 from four times of the smaller. Find the numbers?

  • A.65, 15
  • B.64, 16
  • C.62, 18
  • D.60, 20

Answer: A

Let the smaller be \( y \); the greater is \( 4y + 5 \).

\[ y + 4y + 5 = 80 \quad\Longrightarrow\quad 5y = 75 \]

\[ y = 15, \qquad \text{greater} = 65 \]
