Question

plzz plzz solve this guys ....how many five -digit numbers that can be divisible by 5?​

Answer 1

Step-by-step explanation:

a= 10,000 d=5 n = 99,995

tn = a+(n-1)d

tn = 10,000 + (n-1)d

99,995 = 10,000 + 5n-5

99,995 -5 = 10,000+5n

99,990 - 10,000 = 5n

89,990 = 5n

89,990/5=n

17998 = n

so 17,998 digits are 5 digits numbers divisible by 5
