Basic Mathematics QUESTION #7654
Question 1
A person has Rs 2, Rs 5, and Rs 10 coins amounting to Rs 472. The ratio of the number of Rs 2 coins to Rs 5 coins to Rs 10 coins is 2:3:4. Find the number of Rs 2 coins.
  • \(20\)
  • \(13\)
  • \(8\)
  • None of these✔️
Correct Answer Explanation
Let the number of Rs 2, Rs 5, and Rs 10 coins be \(2x\), \(3x\), and \(4x\). Total amount: \(2(2x) + 5(3x) + 10(4x) = 472\). Simplifying: \(4x + 15x + 40x = 472\), so \(59x = 472\), giving \(x = 8\). Number of Rs 2 coins = \(2x = 2(8) = 16\). Since 16 is not in the options, the answer is 'None of these'.
