Jafar, Mahmud and Rihan have saved an average amount of $s. Jafar has 47 of Mahmud's savings. If Jafar has $188, how much has Rihan's saved?

Step 1: Since Jafar has 47% of Mahmud's savings, and Jafar has $188, we can set up the equation 0.47M = 188, where M represents Mahmud's savings.

Step 2: Solve the equation for M. Divide both sides by 0.47 to get M = 188 / 0.47. This gives us M = $400.

Step 3: The problem states that Jafar, Mahmud, and Rihan have saved an average amount of $s. This means that (Jafar's savings + Mahmud's savings + Rihan's savings) / 3 = s.

Step 4: Substitute the given and calculated values into the equation. We know Jafar's savings (J) is $188 and Mahmud's savings (M) is$400. So, (188 + 400 + Rihan's savings) / 3 = s.

Step 5: To find Rihan's savings, we need to know the value of s. Once we have that, we can rearrange the equation to solve for Rihan's savings: Rihan's savings = 3s - 188 - 400.
