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

### Instruction:
Eddie is 92 years old. His granddaughter Becky is currently four times younger than he is. The mother of Becky - Irene, is two times her age. How old is Irene?

### Response:
 Becky ana umri mara nne mdogo kuliko Eddie, ambayo inamaanisha ana umri wa 92 / 4 = <<92/4=23>>23 miaka.
Mama yake ni mara mbili mkubwa kuliko yeye, hivyo inamaanisha Irene ana umri wa 23 * 2 = <<23*2=46>>46 miaka.
