Question

A sum of money is to the divided among P,Q,R in the ratio 2:3:5 if the total share of P&R together is Rs.400 more than that of Q what is R's share in it?

Answer 1

let share of P, Q & R be 2x,3x & 5x respectively
so from the condition,
2x+5x = 3x + 400
⇒ 7x = 3x + 400
⇒4x = 400
⇒x = 100
⇒5x = 500
so R`s share is Rs. 500

Answer 2

"To find out P, Q & R you must be 2x,3x & 5x respectively

Hence 2x+5x = 3x + 400

⇒ 7x = 3x + 400

⇒4x = 400

⇒x = 100

⇒5x = 500

so R`s share is Rs. 500. Therefore the student can collect the answer for the give values with the suitable formula of P and Q.
