A person has only ₹ 1 and ₹ 2 coins with him. If the total number of coins that he has is 50 and the amount of money with him is 75, then the number of coins ₹ 1 and ₹ 2, respectively are?
Correct Answer: 25 and 25
Explanation:
Total number of coins = 50
Let ₹ 1 coins = x and ₹ 2 coins = y
Now,according to the question,
x + y = 50 ... (i)
and x + 2y = 75 ...(ii)
On solving Eqs.(i) and (ii),we get
x = 25 and y = 25
