How many strings of 5 digits have the property that the sum of their digits is 7?
How many strings of 5 digits have the property that the sum of their digits is 7? total = 10 + 20 + 5 + 60 + 30 + 30 + 60 + 20 + 20 + 30 + 20 + 20 + 5 = 330. So, option (B) is correct. Total number of combinations are (n-1+r)C(r) = (5-1+7)C7 = 11C7 = 11C4 = 330.
How many 5 digit numbers have the sum of their digits greater than 45?
Hence, the answer is (99,999–9,999)/2 = 45,000.
