Little confusion with these questions.

What will be o/p for these two questions one with Write back and the other is Write through.

1.)A 128 word cache and main memory are divided into 8 word blocks. The access time of a cache and main memory are 10ns/word and 25ns/word respectively.
The hit ratio for read operation is 90% and writes operation is 80%. Let there are 60% references for read operations, using write through. What is the average access time?(https://gateoverflow.in/256999/coa-cache-average-access-time)

2.)A 128 word cache and main memory are divided into 8 word blocks. The access time of a cache and main memory are 10ns/word and 25ns/word respectively. 
The hit ratio for read operation is 90% and writes operation is 80%. Let there are 60% references for read operations, using write back. What is the average access time?

What will be the default technique ( write-allocate and no write-allocate)followed for Hierarchal and Simultaneous access ?
