  Answer 1: <b style=”background-color: var(–bb-content-background-color); font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>Ratio of Kavita and Reena amount is 4:3.

  ⇒ Let their shares be Rs.4x and Rs.3x.
  

  ⇒ Then, 3x=2400

  ⇒ x=800

  ∴ Total amount = 4x+3x=7x=Rs.(7×800)=Rs.5600

  ∴ The total amount is Rs.5600.

  Answer 2: =525=5.
