Solution : Given: The sum of the three numbers is 280. The ratio between the first and second numbers is 2 : 3 and the ratio between the second and third numbers is 4 : 5. Let the three numbers be P, Q, and R. According to the question, P + Q + R = 280 P: Q = 2 : 3 Q: R = 4 : 5 Make the ratio equal by multiplying the first ratio with 4 and the second ratio with 3. ⇒ P : Q : R = 8 : 12 : 15 According to the question, $8x+12x+15=280$ ⇒ $35x=280$ ⇒ $x=8$ The second number Q = $12x=12\times 8=96$. Hence, the correct answer is 96.
