### Instruction:
 Samir alipanda ngazi 318 jana. Veronica alipanda 18 zaidi ya nusu ya idadi hiyo. Walipanda ngazi ngapi pamoja jana?

 Nusu ya 318 ni <<318/2=159>>159
159 + 18 = <<159+18=177>>177 ngazi ndizo alizopanda Veronica jana.
318 + 177 = <<318+177=495>>495 ngazi ndizo jumla ya ngazi walizopanda Samir na Veronica jana.
