(A)101 (B)106 (C)184 (D)176​

Answer 1

Answer:

(A) 101

L.C.M.{1,2,3,...,200}

b×L.C.M.{102,103,200}

b=101

b=101 {101,102,....200} takes care of the

L.C.M. of numbers {1,2...200},

L.C.M. of numbers {1,2...200},only 101 is missing.

L.C.M. of numbers {1,2...200},only 101 is missing.Hence, option a is correct
