Answer 23

I think the image is didn't capture the decimal point notice what looks like 10 has a value of 0... so I think its 1.0

Answer 24

i will give an example,tell me if it helps:
log 1.376=0.1386
now u first find 1.3 in that table,u will be looking in that row only
find 7 in middle values ....to get 0.1367
now u find 6 in extreme right,to get 'add 19'
this gives 0.1367+19=0.1386 as final answer
