Question

The Rahul ages of and pushti are in the ratio 3 ratio 5 four years later the sum of their ages will be 48 what are their present ages​

Answer 1

• Rahul is 15, Pushti is 25

Explanation:

Rahul age = r, Pushti age = p

Equations according to given info:

• r / p = 3 / 5 ⇒ r = 3p/5
• r + 4 + p + 4 = 48 ⇒ r + p = 40 ⇒ r = 40 - p

Compare the two equations and solve for p:

• 3p/5 = 40 - p
• 3p = 200 - 5p
• 3p + 5p = 200
• 8p = 200
• p = 200/8
• p = 25

Find the value of r:

• r = 40 - 25
• r = 15
