Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Anna has 50 pencils and Harry has twice the number of Anna’s Pencils but he lost 19 of them. How many pencils are left with Harry?

### Response:
 Anna ana kalamu 50
Harry ana mara mbili ya idadi ya kalamu za Anna hivyo ana kalamu 50 * 2 = <<50*2=100>>100
Hata hivyo, Harry alipoteza 19 kati yao hivyo amebakiwa na kalamu 100 – 19 = <<100-19=81>>81
