Answer 1

`\bold{\boxed{\huge{\blue{\underline{Answer }}}}}`

`\bold{\underline{ Given :- }}`

`\sf{The\: population\: is\: decreased \:by\: 10 percent }`

`\sf{There\: were \: only \: 1800 \: people \: left}`

`\bold{\underline{ To\: Find :- }}`

`\sf{we \: have \: to \: find\: original \: population? }`

`\bold{\underline{ Let's \: Begin :- }}`

`\sf{Let \: the \: total \: population\: be \: x }`

`\sf{\underline{ Therefore }}`

`\sf{According \: to \: the \: question }`

`\sf{ x - 10/100 = 1800 }`

`\sf{ 100x - 10/100 = 1800}`

`\sf{ 100x - 10 = 1800 × 100}`

`\sf{100x - 10 = 180000}`

`\sf{ 100x = 180000 + 10}`

`\sf{ x = 180010/100}`

`\sf{ x = 1800.1 }`

`\bold{\pink{Hence , The\: original \:population \:of \: the\: village \:is \:1800.1 }}`
