$Let\:the\:grandson\:age\:is\:'x'\:years\\\\and\:man\:age\:is\:=10x\:(\because\:man\:is\:ten\:time\:older\:than\:his\:grandson)\\\\So,\\\\According\:to\:the\:question\\\\10x-x=54\\\\\implies9x=54\\\\\implies x=\frac{54}{9}\\\\\implies x=6\\\\\therefore Grandson\:age=6\:yr\\\\and\:man\:age=10\times x\\\\\implies10\times6\\\\=60\:yr\\\\\boxed{\boxed{Grandson\:age\:is\:6\:yr\:and\:man\:age\:is\:60\:yr\:is\:the\:answer}}$
