Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 565.
Calculations:
A box contains 25p and 10p coins in the ratio 6 : 5, amounting to ₹ 226
Let the number of 25p and 10p coins be 6x and 5x
According to the question,
⇒ 25 × 6x + 10 × 5x = 226 × 100
⇒ 150x + 50x = 226 × 100
⇒ 200x = 226 × 100
⇒ x = 226/2 = 113
Required number of 10p coins = 5x = 113 × 5 = 565
