Three persons A, B and C have different amounts of rupees with them. If A takes Rs. 6 from C, A will have an equal amount as B has. A and B together have total Rs. 74. How many rupees does B have?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 40
| Understanding | Application |
|---|---|
|
Suppose A, B, and C have a, b, and c rupees. According to question: a + 6 = b --------- (1) a + b = 74 --------- (2) |
From equation 1 and 2: ⇒ a + (a + 6) = 74 ⇒ 2a + 6 = 74 ⇒ 2a = 74 – 6 ⇒ 2a = 68 ⇒ a = 34 Therefore, b = 34 + 6 = 40 So, B has Rs. 40 |
