Explanation:

• Simplification method in mathematics means reducing the expression in a simpler form using various operations such as addition, subtraction, multiplication and division.
• Simplification mainly allows us to challenge each process and then approach to identify which is the most efficient and best suited way for its specific purpose. Simplification makes an expression into less complicated and easy to understand for solving.

• Given that P has Rs 570 and Q has Rs 350. We want to find how much money should Q receive from P, so that Q has Rs 120 less than 3 times what is left with P.

• Let assume that P must give "k" rupees to Q. i.e., Q receive "k" rupees from P so that, Q has Rs 120 less than 3 times what is left with P.

• According to the question;

350 + k = 3 (570 - k) - 120

⇒ 350 + k = 1710 - 3k - 120

⇒ 4k = 1710-120-350

⇒ 4k = 1240

⇒ k = $\frac{1240}{4}$ = 310

• Hence, the value of k is 310. That is Q receive 310 rupees from P so that, Q has Rs 120 less than 3 times what is left with P.
