This activity follows on from World of Tan 2 - Little Ming.
Good morning, this is Granma T's Removals, Mah Ling speaking. How can I help you?
Oh! You want to know who I am? I'm the personal assistant to Granma T. I run her office, make all the necessary arrangements, manage the workers and do all the accounts. I also keep an eye on those two mischievous scamps, Little Ming and Little Fung, though they are not so little any more!
How old am I? Well, I'm more than three times the age of Little Ming, but I'm the second oldest person here. Numerically, my age is one more than a prime number. My age has eight divisors and three prime factors. So there!
Anyway, that's enough about me. I'll get Granma T to speak to you... please hold...
In the meantime, complete the silhouette of Mah Ling.
- Use the information in the story to work out how old Mah Ling is.
The story continues in World of Tan 4 - Monday Morning.
