N68,000

N65,000
N70,000
설명
5% profit = 100 + 5 = 105%
26% profit = 100 + 26 = 126%
∴ 105% → N60,000
1% → \(\frac{60000}{105}\)
126% = \(\frac{60000}{105}\) x \(\frac{126}{1}\)
= N72,000.
26% profit = 100 + 26 = 126%
∴ 105% → N60,000
1% → \(\frac{60000}{105}\)
126% = \(\frac{60000}{105}\) x \(\frac{126}{1}\)
= N72,000.
