Step-by-step explanation:
The question is asking how many 2 1/2 k stamps can be bought for N5.25. To find the answer, we need to divide the total amount of money, N5.25, by the cost of each stamp, which is 2 1/2 k, or 0.025 Naira when converted to Naira. First, we convert 2 1/2 k to Naira:
- 2 1/2 k = 2.5 k
- 2.5 k = 0.025 Naira (since 1 k = 0.01 Naira)
Now we divide the total amount by the cost per stamp:
- N5.25 / 0.025 Naira = 210
Thus, 210 stamps can be bought with N5.25. The correct answer is d) 210.
