Answer» According to the given questionL.C.M. of two numbers = 3H.C.F of two numbers = 105Then,L.C.M. × H.C.F. = 3 × 105X × Y = 3 × 105 [Because we know that, If X and Y are two numbers then (L.C.M. of X and Y) × (H.C.F. of X and Y) =X × Y]X × Y = 315 ______________ (1) Also given in the question X + Y = 36 _______________ (2) ( X + Y )/(X × Y) =36/315 X/(X × Y) + Y/(X × Y) = 36/315 1/Y + 1/X = 4/35 |
