Numbers divisible by 4 in 1 to 100
= from 1×4=4 upto 25×4 =100 or 25 numbers.
Out of these 25, those that have 4 as a digit are
4 & 24 & 40 & 44 & 48 & 64 & 84 = 7 (Seven) Answer.
Alternatively find such one digit number (only 4) and two digit numbers with 4 only in units place (24, 64, 84) or only in tens place (40, 48) or in both places (44)
