Question

number of integers lying between 1 and 100 that are divisible by either 3 or 7

Answer 1

No . of Numbers from 1-100 divisible by 3 are =>
99 = 3 + (n-1)3
96 = (n-1)3
n = 33

No. of numbers from 1-100 divisible by 7

98 = 7 + (n1-1)7
n = 14

No. of numbers common in n and n1

84 = 21 + (x-1)21

X = 4


Total numbers which are either divisible by 3 or 7 are (33+14)-4 = 43
