The average money P and his seven friends have is ₹450. If P has ₹120 more than the average money of the seven friends, how much money does P have?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 555.
Let the total money of P's 7 friends be 7x.
P + 7x = 3600
Also, P = x + 120
⇒ x = P - 120
Now, P + 7(P - 120) = 3600
⇒ 8P = 4440
⇒ P = 555
